CAUTION • • • • • •

• • • • •

Isolation procedures must be followed when working on equipment.

Isolate any other related equipment where its operation will cause danger to personnel or damage to equipment.

Before operating equipment make sure that nobody is inside or in the immediate area of the equipment.

Maintenance and repair should be undertaken by trained personnel.

Always wear correct PPE when working on hydraulic systems.

Ensure that any relevant circuits are depressurised. Release of high pressure fluids can be fatal. As a final check twist the hose to ensure it is loose before disconnecting fittings.

Always be aware of E-Stop locations, in case of an emergency.

Walkways with anti slip plates and handrails are provided. When using the walkway, operators should monitor face conditions to ensure they do not encounter falling coal.

All guards have to be in place when system is in operation.

High pressure fluids can penetrate skin and enter a human body.

These fluid injections may cause severe tissue damage and loss of limb. If a fluid injection accident occurs, see a doctor immediately.

DO NOT DELAY OR TREAT AS A SIMPLE CUT!

PMC-R Stop Functions The PMC-R’s have a number of keys and buttons that provide the user with control to stop automatic and manual functions and/or remove electrical and/or fluid power to the Shields actuators.

• • • • •

Stop key Emergency Stop Button Emergency Stop Button (Bootend) Local Lockout Button BSL Stop

Stop Key When the “Stop” key is pressed all electrical operations on the PMC-R system are cancelled.

The Stop Key is used to cancel all automatic functions including Batch, Bankpush, Conveyor Pullback, Auto Sequence (ASQ) and suspends SRB operations. The stop key will also cancel any PMC-R that is currently in slave mode when using Adjacent Control or Remote Control. The Dump Valve solenoid connected to the Server PMC-R will remain energised when the Stop Key is pressed.

Emergency Stop When the Emergency Stop Button is pressed all operations are ceased including Adjacent Control, Remote Control, all automatic functions and SRB will be stopped. An SRB new start will be required after an Emergency Stop has been pressed. The Dump Valve solenoid connected to the Server PMC-R will be de-energised when an Emergency Stop is pressed.

Page 24 - 67

M01675-04

North Goonyella – LTCC PMC-R Operating Manual

Emergency Stop (Bootend) If communications are active between the Bootend PMC-R and the Face Server PMC-R then the Bootend PMC-R Emergency Stop Button will cause the same actions as operating an Emergency Stop on the Face PMC-R’s.

BSL Stop External stop buttons can be connected to the Face Server PMC-R these are referred to as a BSL Stop and when operated will cause the same actions as operating an Emergency Stop on the Face PMC-R’s.

Local Lockout Button The Local Lockout Button is used to prevent any electrical operation of the SCU. An additional feature is that when a Local Lockout Button is pressed, the two adjacent SCUs are also to protect operators when standing on or in front of the supports. Power is removed from the solenoid driver outputs on the shield with the Local Lockout Button pressed ‘Locked Out’ while the two adjacent Shields solenoid drivers remain powered but all functions are disabled ‘Soft Locked’. If the Local Lockout Button is pressed on the Face Server PMC-R then only the Face Server will be locked out and the Dump Valve will be de-energised as power is removed from the Face Server’s Solenoid Driver.

Initiate a remote support for slave operation WARNING DANGER: Mine safety procedures in regards to shield movement MUST be observed.

This feature allows operation of a support up to 5 supports away from the operator using the adjacent control functions of the PMC-R. The following exceptions are applied to remote selection of shields.

•

The Buttress shields can only be remotely selected from shield 3 due to the lack of visibility from shields 4, 5, 6 and 7.

•

The roadway shields can select each other remotely. But they cannot select a Buttress shield for remote operation.

•

The BSL PMCR cannot control the Buttress shields. It can only select the Roadway shields via normal adjacent control.

•

The Buttress shields cannot remotely control any other shield.

•

Operation of No.3 support can be achieved via adjacent control from the Bridge PMCR. Pressing the

key on the Bridge PMCR selects No.3 shield.

The outcomes of a Bankpush direction selection

When performing a Bankpush group function in either snake or taper mode it is important that the correct direction (< or >, toggled by the N key) is selected. The direction will determine which end of the group will try to meet the ‘BP extends’ parameter value first.

The example below would shows typical values to perform a TG push at Broadmeadow.

Example 1.

BP: SNAKE 158 > 134 r2 c100 s100 SA-Idle This shows a correctly selected direction, this is also the default direction as the system assumes that the operator wishes to work the snake towards him.

In the above example shield 158 ram stroke will attempt to meet the value of ‘BP extens’. A snake will be formed between 134 and shield 134 + ‘BP snake’. 134 + ‘BP snake’ will target ‘BP extens’ as its final ram stroke.

Example 2.

BP: SNAKE 158 < 134 r2 c100 s100 SA-Idle Bank pushing the face using adjacent group Bankpush

If the face is to be Bank pushed using the adjacent group Bankpush function it is important to understand the maximum amount of shields that you can travel before initiating a fresh adjacent group to ensure all shields receive the BP extens target stroke.

The operator must know the values of the BP Snake and BP group parameters. It can then be determined that the operator must initiate a fresh adjacent group bankpush within every (BP group – BP Snake) number of shields.

M01675-02

Types of Bankpush This parameter is in the Bankpush parameter menu. This parameter sets the default type of push displayed when a bankpush is initiated. The bankpush may also be toggled between the three modes once initiated by using the ’P’ key on the PMC-R keypad.

There are three types of bankpush: (S) Snake

This mode is designed to be used in lieu of the SRB Bank Push and will provide a defined snake over a number of shields. Note that the snake is the last 13 pans in the bankpush group. If you are bank pushing the entire face the bankpush groups must be overlapped to push out the snake.

(T) Taper

Every shield is activated in the defined start and end range and the AFC push will be tapered in the desired direction from 100% to 0 %. NB: Start shield will push 100%.

Page 50 - 67

M01675-04

North Goonyella – LTCC PMC-R Operating Manual (All) All

Every shield is activated for Bankpush. All shields in group try to reach BP extend or push for BP timeout.

Protection zones

During a bank push there is the possibility that a shield is left back causing a neighbour difference between adjacent shields. If this is the case, and a bank push is allowed then physical damaged could be caused to the shield/s. In the following example shield #49 could be damaged by the Bank Push advancing from Left to Right.

To prevent damage to the shields Protection zones are provided. PMC-R software will examine the reading of reed rods. If the linear movement of a reed rod is not in the predefined tolerance the Bank Push will be suspended and reed rod reading re-examined. If however the neighbour difference is in excess of tolerable limits the Bank Push will abort.

This will form a protective curve in the AFC over the group of shields surrounding the shield that had been left back.

Positive set automatic Positive Set Automatic is a function that allows the roof support to reset to the roof or set to the roof after a preset pressure is reached, approximately 120 Bar in most cases.

Positive Set is also used to maintain shield leg pressures within a defined pressure range once the shield has been properly set to the roof.

The positive set function monitors the hydraulic pressure in the shield leg and utilises timers to initiate the positive set function Guaranteed Set The guaranteed set uses the measured leg pressure in a shield and the measured system hydraulic pressure to calculate when to initiate the positive set. In a shield, if measured system pressure > measured leg pressure + PSA p.diff then the positive set activates.

High Pressure Set The high pressure set is activated after a shield auto sequence is complete and the shield has reached setting pressure P2_set.

The high pressure set is also activated after a shield has completed a positive set and reached positive set pressure psa_P2.

Positive Set MUST be turned off if there is poor roof over the rear of the support or the support is used for maintenance purpose.

WARNING DANGER: Positive Set must be turned off if there is poor roof over the rear of the support, or the support is used for maintenance purposes.

It is possible to switch the positive set ON or OFF by pressing With a single push on key `0’ it is possible to switch positive set ON, another push switches the positive set OFF on the support on which you are standing.

NOTICE Note:The ‘0’ key is intended to allow the operator to switch OFF PSA easily if a changing roof condition is noticed local to the shield that requires PSA to be turned off.

Shearer Anti-collision WARNING DANGER: Ignoring ram stroke sensors will defeat anti-collision protection related to the particular ram.

For example a flipper ram stroke sensor that has an ignored reed rod will operate to timers during its automatic extension / retraction. It is possible that the flipper can be fully extended but it will not generate a collision warning with the shearer as its sensor is ignored.

NOTICE Note: Shield Advanced Anti-collision is determined by a shields DA ram stroke in combination with the Shearers Leading drum height (Drum monitor = 1).

As it is also possible for the blockside roadway shield to be in a position where a collision could occur with the shearer drum, protection is in place to generate a collision if the ramstroke values of No.3 DA Ram, No.3 Rear Pull Cylinder and the Blockside Roadway Shields DA ram are not in there expected position when the shearer approaches No.3 shield.

The expected ramstroke values are as follows that will prevent an ‘ACO Roadway Collision’ from occurring.

1.

Block side roadway shield DA stroke is less than ‘ACO RWBlockStroke’ parameter value.

2.

No.3 shields RCP cylinder is less than ‘ACO RWBlockStroke’ parameter value.

3.

No.3 shields DA cylinder is greater than ‘ACO RWBlockStroke’ parameter value.
