穿煤层倾斜巷道支护技术研究
|
摘要
由于煤层地质条件复杂,部分巷道在掘进过程中,出现穿煤层的情况,为解决巷道穿煤层时支护困难的问题,以山西贺西煤矿3316高抽巷地质条件为基础,采用理论分析的方法,对巷道穿煤层时围岩结构的类型以及支护原理进行了研究与分析,针对性的提出了巷道支护方案,并在现场进行了实践,实践效果表明该支护方案能够有效的保证巷道的稳定性,减小围岩破坏情况,取得了较好的现场效果。
Due to the complicated geological conditions of coal seams, some coal mines have encountered coal seams during the excavation process. In order to solve the problem of difficult road support when crossing the coal seam, the theoretical analysis method is adopted based on the geological conditions of the 3316 high pumping roadway in Hexi Coal Mine, Shanxi. The type and support principle of the surrounding rock structure when the roadway penetrates the coal seam is studied and analyzed. The roadway support scheme is proposed and implemented on the spot. The practical effect shows that the support scheme can effectively guarantee the roadway. The stability of the surrounding rock is reduced and the field effect is achieved.
