现代煤矿安全生产中,煤与瓦斯突出矿井必须开掘底抽巷,用于运输顺槽条带和综采工作面回采区域瓦斯治理。岩巷综合掘进方式可减少人力物力的投入,加快掘进速度,提高企业的效益。采用综合掘进采掘,能够实现岩石连续切割、装载、运输的一条线作业。本文就岩巷综合掘进方式进行分析。1岩巷综合掘进的设备1)岩巷地质情况该巷道设计布置在太原组上段L8灰岩及以下粉砂岩等岩层中,层位较为简单,岩层走向40°~50°、倾向130°~
In the modern coal mine safety production, coal and gas outburst mines must dig bottom draining alley, which is used for gas treatment in transportation tangent strip and fully mechanized coal mining face. Comprehensive tunneling method can reduce the investment of manpower and material resources, accelerate the speed of excavation and improve the efficiency of enterprises. The use of integrated mining excavation, rock continuous cutting, loading, transportation of a line operation. This paper analyzes the comprehensive tunneling method. 1 Rock Tunnel Comprehensive Tunneling Equipment 1) Geological Conditions of Rock Roadway The roadway is designed and arranged in L7 limestone and the following siltstone and other rock formations in the upper section of Taiyuan Formation. The strata are relatively simple with the strike of 40 ° ~ 50 ° and the trend of 130 ° ~
