摘要
靖远煤业集团公司大水头煤矿煤层厚、煤质松软、瓦斯含量高,机掘锚网支护巷道成形较难控制,影响工程质量,对安全生产埋下隐患。文章从大水头煤矿影响机掘巷道成形的因素入手,提出了高瓦斯特厚软煤层机掘巷道控制成形、提高工程质量和消除安全隐患的一系列有效可行的对策与做法,具有一定借鉴性。
According to the situation of coal thick, soft, high gas content, machine digging anchor net supporting roadway forming is diffi- cult to control, affect the quality of the project, the safety hidden danger in production in Dashuitou Coal Mine of Jingyuan Mining Group. This paper analysis on the influencing factors of the mine roadway forming starting from Dashuitou Coal Mine, it proposed high gas thick soft coal seam tunnel control forming, and it improved the security of a series of effective and feasible countermeasures and methods of engineering quality, eliminate the present,it has a certain reference.
