摘要
某矿近距离煤层顶板破碎,巷道难支护易出现冒顶等事故,基于该矿近距离煤层工程概况,分别从优化巷道掘进参数,详细勘察地质构造等方面提出了一些预防掘进巷道冒顶的措施,并提出了架棚巷道冒顶与锚网巷道冒顶的处理措施,通过对掘进巷道冒顶事故进行事前预防与事后处理,可有效防治复杂地质条件下的掘进面冒顶事故,更好的保障近距离煤层安全掘进。
In a mine,the roof of the close-distance coal seam is broken,and the roadway is difficult to support and prone to roof fall.Based on the general situation of the close-distance coal seam project in this mine,some measures to prevent roof fall of the roadway are put forward from the aspects of optimizing the tunneling parameters and investigating the geological structure in detail,and the treatment measures of roof fall of the shed roadway and anchor net roadway are put forward.The roof fall accident of the roadway can be effectively prevented and controlled under complex geological conditions,and the safe driving of the close-distance coal seam can be better guaranteed.
