CIL makes safety audit mandatory at its mines
Coal India Limited (CIL) has made safety audit of its mines mandatory at regular interval to make coal mining safer and check accidents. It has already drawn Risk Assessment & Safety Management Plan and Risk Assessment has been completed in most of CIL mines, the coal ministry said.
CIL has identified potential hazards associated in mining activities due to existing geo-mining conditions, method of mining being adopted and machineries being used.
CIL has also established a structured multi-disciplinary Internal Safety Organization (ISO) to assist the line management at various levels in matters related to safety. “Time-bound action programmes to eliminate or to reduce or to avoid the identified risks for each mine has been chalked out along with review mechanism,” the ministry said.
Apart from complying with the statutory provisions as laid down in the Mines Act, 1952 and the Coal Mine Regulations, 1957, Mine Rule and bye laws framed there under, the following steps have been taken/being taken by CIL to ensure safe coal mining:
Steps for disaster prevention:
Inundation: Thrust on safety audit, check survey, trials of geo-physical methods for detection of water bodies / proving parting etc.
Fire in mines:
• Panel system working (so that in case of fire that can be isolated immediately),
• Regular inspection
• Strengthening of isolation stopping
• Inspections are made as per provisions of CMR-1957 and technical circular issued by DGMS time to time
• Impart training to all concerned
• Early gas detection through various modern gadgets (both sensors and catalytic base), continuous type computer based on-line gas monitoring for highly gassy and fiery mines and erection of explosion proof stopping.
• Emergency action plan has been prepared and mock rehearsals are being carried out regularly.
Reduction of roof/side falls accident:
• Stress on face mechanization to reduce exposure of workmen in active working zone
• Support plan based on rock-mass-rating (RMR) of over-lying roof strata
• Greater use of roof bolting for roof support
• Introduction of mechanized drilling by advanced roof bolting machines
• Introduction of resin capsules
• Emphasis on development of indicators for detecting impending load on roof through R&D
Reduction of accident at opencast as well as on surface of mines:
• Mine-specific traffic rule
• Code of practices for HEMM operators, maintenance staffs, and others
• Standard procedures related to safe operation of various mining operation
• Risk assessment and management
• Training of contractor’s workers involved in transporting operation
