摘要
以石炭井二矿21053工作面为例,探索在倾斜煤层沿空掘巷中应用锚网索支护技术,通过对表面位移、围岩深部位移和锚杆(索)受力进行现场监测,分析了倾斜煤层中沿空巷道矿压显现规律和锚杆(索)受力特性。
For the example of 21053 mining face, the paper researchs the application of bolt -mesh -cable support technology in gob - side roadway excavating in incilined seam. By monitoring the strata displacement and bolt / cable pressure, the article analyses the law of ground pressure hehavior and bolt / cable pressure, analyses the law of ground pressure hehavior and bolt / cable pressure characteristics of roadway behind god in incilined seam.
