Coalbed Methane Development and Technical Access in China Coal Mining Area

Based on the introduction on the condition of the coalbed methane resources distribution and utilization in China and the key mining areas and the coalbed methane development principle of the mining area,the paper analyzed the time and space coordinated relationship of the coal and coalbed methane integrated development and the technical access of the coal and gas simultaneous mining in the coal mining area. From the time and space law of strata movement caused by seam mining,the seam mining affected to the layout of the coalbed methane well( borehole) and the promotion role of the coal mining operation to coalbed methane development,the paper analyzed the coal mining affected to the coalbed methane development. From the coalbed methane development affected to the coal mining sequence and efficiency,the promotion role of coalbed methane drainage to mine gas control and the safety hidden danger left by coalbed methane surface development,the paper analyzed the coalbed methane development affected to coal mining. The paper introduced the coalbed methane development effect in the coal mining area and pointed out that the coal and gas integrated coordinative development would be the effective access to develop and utilize the two resources in coal mining area and to prevent and control mine gas accident.
