摘要
通过对补连塔煤矿22307工作面受上覆采空区漏风影响程度的分析,并结合工作面生产情况,确定22307工作面在开采过程中受采动影响可能与上覆12煤采空区存在沟通裂隙,导致漏风通道复杂,增大22307工作面上覆采空区自然发火的危险。为此,先后采取预防性注浆工程、地表裂隙封堵、加强防火密闭管理等措施对火区进行了综合处理,保证工作面的安全回采。
Based on the analysis of the influence of air leakage from the overlying goaf at 22307 working face of Bulianta Coal Mine and the production situation of the working face,it is determined that the 22307 working face affected by mining may have a communication crack with the overlying 12#coal goaf.As a result,the air leakage passage is complicated,which increases the risk of spontaneous ignition in the goaf overlying the 22307 working face.For this reason,preventive grouting engineering,surface crack sealing,strengthening fire prevention and sealing management and other measures have been taken to comprehensively deal with the fire area to ensure the safety of the working face.
