摘要
本文阐述了高位钻孔抽放的基本原理和特点,利用数值模拟分析了采动影响下的特厚煤层上覆顶板岩层裂隙分布特征,并通过水帘煤矿3801综放工作面的高位钻孔抽放实验,对比论证了高位钻孔抽放的可行性,为特厚煤层的安全高效开采提供了保障。
The paper expound the basic principle and characteristics of high level borehole drawing. Making use of the result of numerical simulation analyze the overlying roof strata＇s distribution feature of cracking which influenced by mining extremely thick coal seam, and through the high level borehole＇s drawing experiment in the fully mechanized caving face of the Shuilian coal mine, contrastive demonstrating the feasibility of the high level borehole drawing, and providing guarantee for safety and high efficient coal mining.
