REASONS FOR ROOF & SIDE FALL

ACCIDENTS.

PLANNING ISSUES IN DEVELOPMENT

DEVLOPMET WITH OUT CONSIDERING FLOOR CONTOURS.

NOT FRAMING SSR IN SCIENTIFIC WAY. WIDER GALLARIES & INADEQUATE SUPPORTS. STABILITY OF SIDES & SUPPORT DESIGN. VALIDATION OF RMR & SUPPORT PLANS. DESIGN OF SUPPORT SYSTEMS FOR

GEOLOGICALLY DISTURBED AREAS. TRAINING & SKILL IMPROVEMENT.

2.PLANNING ISSUES IN DEPILLARING PANELS

WIDER PANELS /LONGER DIAGONAL LENGTHS. WIDER GALLERIES. MORE HEIGHT OF EXTRACTION. LONGER DURATION OF SLICING /SLOW RATE OF EXTRACTION. INDUCED BLASTING TO PREVENT HANGING GOAF. IMPROPER STOWING SYSTEMS. INFERENCING THE DATA COLLECTED FROM INSTRUMENTATION. NON COMPLAINCE OF PERMISSION CONDITIONS.

3.IMPLEMENTATION ISSUES TESTING AND DRESSING OF ROOF & SIDES

BEFORE & WHILE WORKING. INSPECTION,TESTING,DRESSING & SUPPORT

OF TRAVELLING AND HAULAGE ROADS. INADEQUATE TEMPORARY SUPPORTS. MISS JUDGEMENT BY MINE OFFICIALS. TESTING OF ROOF BOLTS & ROPES. TIGHTNESS OF SUPPORTS. SUPPORT CYCLE IN MINES. MEETINGS WITH MINE OFFICIALS. INTERACTION WITH SUPPORTMEN etc.

CORRECTIVE ACTIONS SUGGESTED

103 CIRCULARS WERE ISSUED TO CONTROL ACCIDENTS FROM ROOF & SIDE FALLS,METHOD OF WORKING etc.

STANDARDIZING ROOF BOLTING METHODS. MECHANIZED DRILLING FOR BOLTING. SWITCHING OVER TO RESIN GROUT IN ALL

PLACES. TESTING GROUT MATERIALS & BOLTS. CALCULATING FRESH RMR OF ROOF AND RE-

DESIGNING SSR SCIENTIFICALLY.

CORRECTIVE ACTIONS SUGGESTED.

SUPPORT REQUIREMENTS OF SIDES. FRAMING OF EFFECTIVE SAFETY

MANAGEMENT PLAN FOR EVERY ACTIVITY IN THE MINE & IT’S IMPLEMENTATION.

REVIEW SOPs PERIODICALLY AND UP-DATE AS SUTUIATION WARENTS.

STANDERDIZATION OF MONITORIG INSTRUMENTS.

UTILIZING THE INFORMATION FROM PREVIOUS EXPERIENCES.

Concern for man and his fate must always form the chief interest of all technical endeavors. Never forget this in the midst of your diagrams and equations. Albert Einstein
