SAFETY IN COAL MINES

 

Jharia & Raniganj Action Plan

 

         The problems of subsidence and fires are the result of unscientific mining carried out by the earstwhile mine owners over more than 200 years of operations in these coalfields of Jharia and Raniganj prior to nationalisation.  The population living in the old mining areas has increased many times over the years, though these areas became unsafe for habitation.  In-spite of the declaration of these areas unsafe by the local administration, the habitation increased unabated. The problem of subsidence and fire are being addressed by the Government from time to time.  In this regard a High Level Committee was set up in December, 1996 under the Chairmanship of the then Secretary, Ministry of Coal with representatives from other Departments, Coal companies and the concerned State Governments to deal with the problem in a comprehensive manner.  Based on the recommendations of the Committee a Master Plan was prepared to deal with the problems of fire and subsidence and related rehabilitation covering the areas under Bharat Coking Coal Ltd. (BCCL) and Eastern Coalfields Ltd. (ECL) in 1999 for implementation of the same in a phased manner.

 

                       The Government has approved the Master Plan dealing with fire, subsidence and rehabilitation and diversion of surface infrastructure within the leasehold of Bharat Coking Coal Limited (BCCL) & Eastern Coalfields Limited (ECL) on 12th August, 2009 at an estimated investment of Rs.9773.84 crores (Rs.7112.11 crores for Jharia Coal Field (JCF) and Rs.2661.73 crores for Raniganj Coal Field (RCF) including Rs.116.23 crores sanctioned earlier for various Environmental Measures & Subsidence Control (EMSC) schemes. The summarized data of approved Master Plan is given in the table below:

            Asansol-Durgapur Development Authority (ADDA) and Jharkhand Rehabilitation Development Authority (JRDA) have been notified by the state Governments of  West Bengal and Jharkhand respectively as implementing agencies for rehabilitation purposes.  Coal companies (ECL & BCCL) will provide technical support and the outlay will be funded partially through the internal resources of CIL and the cess collection under CCDA.

 

                          The implementation of the Master Plan for Jharia and Raniganj Coalfields is being monitored by the High Powered Central Committee (HPCC) constituted by this Ministry under the chairmanship of Secretary (Coal). So far, six meetings of the Committee have been held. More than 50% of survey works has already been completed for rehabilitation of the affected persons.  In BCCL area, out of 595 nos. of sites, demographic/socio-economic  survey of 333 sites have been completed and Photo Identity Cards of 23334 families are complete till 30-10-12.   2352 houses have been constructed, in which 1133 families have shifted till 30-9-12.   For shifting of BCCL employees 344 houses have been built in non-coal bearing zone and another 1152 triple storied quarters (96 Blocks each of 12 units) are under construction in various non-coal bearing zones. Further, Demographic Survey of 104 locations has been completed out of 141 identified unstable locations in Raniganj Coalfield Area under ECL.

 

     SAFETY MEASURES / INITIATIVES

 

                          Safety in coal mines is of paramount importance in addition to the compliance of the provisions of prescriptive safety legislation under the Mines Act 1952, PSU coal companies have also taken steps for self regulation.  These steps includes:-

 

v  Establishment of multi-disciplinary Internal Safety Organization (ISO) to assist the line management at various levels in matters related to Safety.

v  Introduction of Risk Assessment based Safety Management Plan for their mines.

v  Safety Audit by independent safety auditors.

v  Steps for Disaster Prevention:

o   Inundation: Thrust on Safety Audit, Check Survey, Trials of Geo-physical Methods for detection of water bodies / proving parting, adequate preparation before monsoon season etc.

o   Fire in mines: Panel system working (so that in case of fire that can be isolated immediately), construction of isolation stopping where development of pillar was done without panel system, strengthening of existing isolation stoppings and use of fire retardant sealant, use modern gadgets for early detection fire/ spontaneous heating etc. Emphasis on use of Gas Chromatograph for analyzing mine air more accurately.

o   Explosion: Early Gas detection through various modern gadgets (both sensors & catalytic base), Continuous type computer based on-line Gas monitoring for highly gassy and fiery mines and erection of explosion proof stopping.

 

Emergency Response Systems

o   Emergency Action Plans (EAP) of each mine are being reviewed from time to time and corrective action taken.

o   Mock Rehearsals for examining the efficacy of Mine-wise Emergency Action Plan.

o  .Demarcating Escape Routes: An exercise for demarcating Escape Routes in underground mines, on plans as well as belowground by fluorescent paint, display of the same at the entry to the mine has been done.

o   State of the art Rescue Apparatus like BG-4 Self Contained Breathing Apparatus was introduced in Rescue Stations and Rescue Personnel were trained for their use.

 

For reduction of Roof/Side falls accident:  Roof / Side fall accident is still one of the major causes of fatal accident in underground mines. Coal Companies have given priority for ensuring roof support management through :

o   Stress on face mechanization to reduce exposure of workmen in active working zone.

o   Geo-mechanical properties of overlying rocks are being studied and Support Systems are being scientifically designed on the basis of Rock-Mass-Rating (RMR) of overlying strata and duly approved by DGMS.

o   Strata Control Cells have been established in all coal subsidiaries.

o   Introduction of mechanized drilling by roof bolting machines.

o   Emphasis on development of indicators for detecting impending load on roof through R&D.

o   Replacement of grouting material from cement to fast setting resin capsules.

·         Following Strata Monitoring Instrumentation have been introduced in some of mines:

o   Tell Tale (Duel Height, Rotary type)

o   Load Cell

o   Rib and Bore Hole Extensometer,

o   Remote convergence indicator

o   Magnasonic Extensometer

o   Pressure Gauge

 

For reduction of accident in Opencast as well as on Surface of Mines: The following measures are being taken for reduction of fatalities in Opencast Mines & on Surface:

o   Mine-specific Traffic Rule.

o   Code of Practices for HEMM operators, Maintenance staffs & others.

o   Standard of Procedure related to safe operation of various mining operation.

o   Risk Assessment & Control Management related to opencast activities.

o   Training of Contractor’s Workers involved in transporting.

o   Procurement of advanced surveying/slope monitoring devices.

 

Monitoring the status of safety through the following agencies :

o   Workmen’s Inspectors

o   Safety Committee at mine level

o   Area Level Bipartite/Tripartite Committees

o   Bipartite/Tripartite Safety Committees

o   CIL Safety Board        

o   Standing Committee on Safety in Coal Mines

o   National Conferences on Safety in Mines

o   Different Parliamentary Standing Committee
