MANDATE

• To carry out R & D activities in the field of rock mechanics and mining methods and mine environment and safety.
• To develop mine machinery equipment and instruments to make mining safe, productive, environmental-friendly and productive.
• To develop ways of reducing environmental pollution due to mining, and minimizing health hazards to miners.

MAIN FACILITIES

• Testing of materials for their chemical components and physical and mechanical parameters; testing of wire rope, cage and suspension gear components and other mining machine parts.
• Composition analysis of coal and areas and minerals of various types.
• Testing of electrical equipment used in mines, petrochemical and fertilizer industry with regard to their flame and weather proofness; testing of flammability of various products used in mines.
• Certification and testing of explosives and accessories for use in underground mines.
• Testing of physio-mechanical properties of rock and coal samples.
• Facilities of computer modelling.
• Database on information relating to the country's mineral resources and mining industry.

SIGNIFICANT ACHIEVEMENTS                          

• CMRI work on cable bolting and underground pillar design has helped in the recovery of otherwise difficult to extract coal from Indian coal mines.
• The long wall mining technique perfected by CMRI has helped in the successful adaptation of mechanized long wall systems over diverse geomining conditions.
• Modification, improvement and adaptation of various new techniques such as narrow panel system of mining, wide stall mining, inclined slicing, with mixed support, etc., have enabled extraction of coal under complex mining conditions e.g. under surface structures and water bodies.
• Prediction and control subsidence based on two- and three- dimension numerical modelling and field observation have helped the mining industry to extract coal underneath and in vicinity of surface features and structures, railway lines, water bodies, etc.
• Design of new hydraulic stowing systems and improvement of existing stowing plants for coal mining and of the method of back fill in mines have improved the mining productivity.
• Improvement in technology of ventilation network planning including the development of multizonal ventilation system, and utilization of the technique of pressure balancing have improved the working environment and safety in mines.
• Safe design and stabilization of tunnels, roadways, hydraulic dams and underground structures and associated underground excavations in plains and hilly areas.
• Monitoring and control of blasting biodegasification , fire hazards and its control, air and water pollution assessment and its control, communication and data monitoring, design and development of mining equipment and instruments, machine condition monitoring, an duplication of cryogenic technology for control of coal mine fire and quick reopening of mines.
• Reclamation and use of mine waste.
• Land use evaluation and management through remote sensing.
• Hydrological studies for supply of safe drinking water in mining areas.
• Design and construction of a model low-cost house for slum dwellers.
• The equipment/machineary developed include: high set remote prop,; digital temperature indicator; data acquisition and mine management systems; release device for steel rigid prop; surface air lock; low cost hydraulic prop; coal getting machine; roof bolt setter; cable bolt for depillaring of thick coal seams; heat resistant explosive composition; low power and portable data logger; and environment-friendly waste loading system.
