摘要
为保障矿山安全生产,通过对煤峪口煤矿8701综采工作面煤层赋存以及顶底板情况分析,确定8701综采工作面采用走向长壁后退式一次采全高综合机械化采煤方法,全部垮落法处理顶板。根据同煤层矿压观测选择及本工作面矿压参数统计,从矿压参数、支架选型计算对工作面进行合理的支护设计。对正常回采时采空区控制和特殊时期的顶板控制进行分析,为实际生产提供安全保障。
In order to ensure the safe production of mine,through the analysis of the coal seams and the conditions of the top and bottom plates of the 8701 fully mechanized coal mining face in Meiyukou Coal Mine,it is determined that the 8701 fully mechanized mining face adopts the long-wall retreat-type one-time full-height comprehensive mechanized coal mining method,all of which are degraded.The roof is treated.According to the mining pressure observation selection of the same coal seam and the statistics of the mining pressure parameters of the working face,the reasonable support design of the working face is carried out from the calculation of the mining pressure parameters and the support selection.The control of the goaf during normal mining and the roof control during special periods are analyzed to provide safety for actual production.
