掘进巷道爆破法过断层施工工艺研究应用

Research and Application of Blasting Technology in Tunneling Roadway Passing Through Fault

巷道在掘进过程中遇断层破碎带时若不采取合理有效的施工工艺、支护工艺及安全技术措施,不仅降低巷道掘进效率,而且很容易发生重大煤矿安全事故。对此山西宏宇诚铸建设工程有限公司塔山矿建项目部在施工2105巷时,通过技术研究决定采用炮掘过断层构造区,制定相应的安全技术措施,保证掘进巷道安全顺利过断层破碎带。

If there is no reasonable and effective construction technology, support technology and safety technical measures in the course of tunnel excavation, it can not only reduce the effciency of roadway driving, but also easily take place major coal mine safety accidents. To solve these problems, the project department of Tashan Mine of Shanxi Hongyu Chengzhu Construction Engineering Co., LTD., after many researches, decided to adopt blasting method to pass through the fault structure, in the construction of 2105 roadway, and puts forward the corresponding safety technical measures to ensure the tunneling roadway passes through the fault fracture zone smoothly and safely.
