摘要
由于勘探手段单一,勘探精度有限,不能勘探到一些特殊的隐伏地质构造,这使得在巷道掘进过程中揭露特殊地质构造时需要制定特殊的施工方案。15102胶带巷在掘进过程中揭露一条长轴约23m的陷落柱,且过陷落柱后煤层受构造影响,倾角发生急剧改变。针对这种情况,对15102胶带巷进行挑顶压底重新掘进巷道过陷落柱及穿越岩层找煤。详细地介绍了挑顶巷道重新掘进找煤的施工方案,并制定了一系列安全措施,可以为掘进巷道过地质构造提供一定的参考。
Due to the single exploration means and the limitation of exploration accuracy,some special hidden geological structures cannot be explored,which makes it necessary to formulate special construction plans when exposing special geological structures during the process of roadway excavation.During the excavation of 15102 belt roadway,a collapse column with a long axis of about 23 m was exposed,and the dip angle of the coal seam changed sharply after passing the collapse column due to the influence of the structure.In view of this situation,the 15102 belt roadway was re-driven through the collapse column by roof brushing and bottom pressing and through the rock stratum to find coal.This paper introduced in detail the construction scheme of re-driving and coal prospecting for the roof brushing roadway,and formulated a series of safety measures,which can provide a certain reference for the geological structure of the tunneling roadway.
