摘要
断层的存在不仅影响巷道掘进速度,而且容易引发一系列安全事故。根据兴陶煤业有限公司二水平三采区运输大巷掘进过断层为实例,采用临时支护、永久支护、锚杆+锚索+钢带+钢筋焊接网、架棚支护等联合支护方式,实现对围岩的有效控制,保证巷道掘进过程中的安全、顺利。
The existence of fault not only affects the speed of roadway excavation, but also easily causes a series of safety accidents. According to Xingtao coal industry Co., Ltd. two level three mining area transportation roadway driving through the fault as an example, the use of temporary support,permanent support, bolt + anchor cable + steel belt + steel welded mesh, shed support and other joint support methods, to achieve effective control of surrounding rock, to ensure the safety and smooth roadway excavation process.
