古书院矿15#煤层在开采过程中,工作面采用U型通风方式,此种通风方式易出现上隅角瓦斯超限问题,影响工作面正常回采。在对该矿152303工作面“U型”通风系统瓦斯运移规律和顶板岩层采动裂隙发育规律进行深入研究的基础上,提出一套以邻近层瓦斯抽放方案与该煤层瓦斯抽放方案相结合的立体瓦斯抽放治理体系,此立体抽放体系可为其它工作面提供技术参考,保证矿井安全生产,解决生产衔接问题。
古書院礦15#煤層在開採過程中,工作麵採用U型通風方式,此種通風方式易齣現上隅角瓦斯超限問題,影響工作麵正常迴採。在對該礦152303工作麵“U型”通風繫統瓦斯運移規律和頂闆巖層採動裂隙髮育規律進行深入研究的基礎上,提齣一套以鄰近層瓦斯抽放方案與該煤層瓦斯抽放方案相結閤的立體瓦斯抽放治理體繫,此立體抽放體繫可為其它工作麵提供技術參攷,保證礦井安全生產,解決生產銜接問題。

In the process of mining of 15# coal seam in Gushuyuan Mine, U-shaped ventilation way was used in mining working face, which often appears gas overrun problem in upper corner of roadway, and affects the normal in mining working face. Based on the study on the rule of gas migration and mining roof strata fracture in 152303 working face with"U"type ventilation system, this paper put forward a set three-dimensional gas drainage management system that was combined the adjacent layer gas drain-age plan with this coal seam gas drainage scheme. The three-dimensional drainage system can provide technical reference for other working face, ensure the safety of mine production, and solve the production problems.
