摘要
通过分析鹤煤公司三矿综放工作面采动对煤层顶板变形破坏、煤岩层卸压、透气性增加、瓦斯解吸运移的影响,论述了利用煤层高位顶板走向钻孔抽采瓦斯技术的可行性。该技术在鹤煤三矿3008厚煤层综放工作面应用,取得了较好的瓦斯治理效果。对于类似开采条件下的瓦斯防治,具有较高的借鉴价值。
Mining-induced subsidence in fully mechanized caving face in No. 3 Coal Mine of Hebi Coal Industry Co. has some effects to the deformation and damage of coal seam roof, the stress-relaxing of coal and rock seam, the increasing of coal seam permeability and the desorption and migration of coal gas. By analyzing these effects,this article discussed and studied the feasibility of gas extraction by the technology of drilling along strike direction in coal seam＇s high-level roof. It has obtained good effect of thick coal seam gas control in 3008 fully mechanized caving face in No. 3 Coal Mine of Hebi Coal Industry after using this technology. It has significance referential value for gas control under similar mining conditions.
