摘　　要：在介绍我国及重点煤矿区煤层气资源量分布利用情况以及煤矿区煤层气开发原则的基础上,分析了煤矿区煤与煤层气一体化开发的时空协调关系及煤气共采实现的技术途径。从煤层采动引起的岩层移动时空规律、煤层采动对煤层气钻井(孔)布设的影响和采煤活动对煤矿区煤层气开发的促进作用3个方面分析了煤炭开采对煤层气开发的影响;从煤层气开发对煤炭开采顺序和效率的影响、煤层气抽采对煤矿瓦斯治理的促进作用以及煤层气地面开发存在的安全隐患3个方面,分析了煤层气开发对煤炭开采的影响。最后介绍了煤矿区煤层气开发的效果,指出煤与煤层气一体化协调开发是开发和利用煤矿区2种资源,预防和治理煤矿瓦斯事故的有效途径。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 rela- tionship 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 eoalbed 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 eoalbed 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 meth- ane development effect in the coal mining area and pointed out that the coal and gas integrated coordinative development would be the ef- fective access to develop and utilize the two resources in coal mining area and to prevent and control mine gas accident.
