摘要
以新建矿井升富煤矿为例,在确定评估煤层的基础上,运用地勘煤层瓦斯分带的角度进行分析,结合煤层赋存特征、地质构造条件、地勘钻孔瓦斯动力现象等情况进行煤层瓦斯地质分析,并利用地勘资料中测定的煤层瓦斯含量,修正筛选得出地勘煤层瓦斯含量最终值分析的方法,依据相关行业规范、标准的有关规定对升富煤矿主采的2^-2、3^-1煤层煤与瓦斯突出危险性进行综合评估确定,评估结论为主采2^-2、3^-1煤层不具有煤与瓦斯突出危险性,上述评估方法对可研阶段的新建矿井煤层的煤与瓦斯突出危险性评估具有借鉴意义。
Taking the newly-built mine Shengfu coal mine as an example,on the basis of determining the evaluation of coal seams,the coal seams are analyzed by using the angle of gas zoning of the coal seam,combined with the characteristics of coal seam occurrence,geological structural conditions,gas dynamics of geological prospecting and drilling,etc..Gas geological analysis,combined with the determination of coal seam gas content measured in geological prospecting data,the method of analyzing and finalizing the final value of gas content in geological exploration coal seam,according to the relevant industry norms and standards,the main mining of Shengfu coal mine 2^-2,3^-1 coal seam coal and gas outburst danger comprehensive evaluation and determination,the conclusion is that the main mining 2^-2,3^-1 coal seam does not have the risk of coal and gas outburst,the above evaluation method for the new mine shaft in the feasibility study stage.The coal and gas outburst risk assessment can be used for reference.
