摘要
文章结合太原麦地掌煤矿中厚煤层的地质分布特点和开采目标,围绕110工法所成巷道质量坚固、能够有效阻隔采空区不平衡压力传递并降低巷道充填及维护成本等优势,研究了110工法关键技术在中厚煤层中的应用方法,同时通过质量跟进检查对工法实施过程进行了修正,实现了经济和社会双重效益的提升。
This paper combines the geological distribution characteristics and mining objectives of the medium-thick coal seam in Taiyuan Maidizhang Coal Mine, and investigates the application of the key technologies of the 110 method in medium-thick coal seams, focusing on the advantages of the 110 method, such as the robust quality of the roadway, the ability to effectively block the unbalanced pressure transfer in the mining area, and the reduction of roadway filling and maintenance costs. The process of implementing the method has been revised through quality follow-up checks to achieve both economic and social benefits.
