Bidirectional Cutting Cycle Beginning at Headgate

Bidirectional Cutting Cycle – Step 7 – Shearer in HG

R e s t r i c t i o n s

SRB is not subject to the standard restrictions; however, the actions that SRB triggers are subject to the restrictions defined for each type of action. SRB cannot be initiated and will abort (err: "SRB FACE AUTOMATION aborted") for a Quickstop and for an Incomplete Network.

Parameter Summary

Infrared Tracking

To run Inrared tracking, change this value to On. If Serial or Manual are selected it will change this option to off.

Manual Tracking

To run Manual tracking, change this value to On. If Infrared or Manual are selected it will change this option to off.

Beginning Shield 1-30

First shield on face that SRB will control.

Ending Shield from TG 1-30

Number of shields from TG that marks last shield that SRB will include. (1 means last shield; 2 means next to last shield, etc.)

H->T Asq All, None

Toggle ASQ options for head-to-tail pass.

H->T Push Mode All, None

Toggle push options for head-to-tail pass.

H->T Push Trig Shld 1-310

Begin pushing when shearer reaches this shield. Set high to delay push.

H->T Push Reverse On, Off

Reverse the push once the shearer reaches the Trig Shield and follow normally from that point; most useful when H->T Trig Shld is set high.

H>T Push Protection Full, None

Set level of conveyor protection during SRB push for H->T pass.

T->H Asq All, None

Toggle ASQ options for tail-to-head pass.

T->H Push Mode All, None

Toggle push options for tail-to-head pass.

T->H Push Trig Shld 1-310

Begin pushing when shearer reaches this shield. Set low to delay push.

T->H Push Reverse On, Off

Reverse the push once the shearer reaches the Trig Shield and follow normally from that point; most useful when T->H Trig Shld is set low.

T>H Push Protection Full, None

Sets the level of push protection when mining from the tail to the head running SRB. This does not affect the bankpush protection.

Manual Safety Zone 0-10

Distance away from shearer position that first shield ASQs.

Auto HG Safety Zone 2-15

Dist away from shearer pos that first shield ASQs (on HG side).

Auto TG Safety Zone 2-15

Dist away from shearer pos that first shield ASQs (on TG side.)

Push Dist Behind Prime 1-15

Dist that separates ASQs and conv push.

HG Cleanup Area 5-20

Size of HG area where shearer can move without triggering ASQs.

HG Turn Point 1-25

Set to lowest shield number that shearer will reach every time it cuts out at HG.

HG DoubleCut Point 10-40

Shield number that shearer must come to on HG double cut.

HG Readvance Group 0-15

How many HG shields will readvance after the HG push.

Start Push at Shield # 1-30

First shield at HG that SRB is allowed to push.

TG Cleanup Area 5-20

Size of TG area where shearer can move without triggering ASQs.

TG Turn Point from TG 1-25

Number of shields from the TG that marks the point the shearer will reach every time it cuts out at the TG.

TG Dblcut Pt from TG 10-40

Number of shields from the TG that marks the point the shearer must come to on TG double cut.

TG Readvance Group 0-15

How many TG shields will readvance after the TG push.

Max # of ASQs 3-30

Limit on number of ASQs that SRB will trigger behind the shearer.
