摘 要:新疆榆树岭110503回采工作面属于Ⅱ类自燃煤层,随着开采深度的增加,工作面采空区自然发火危险性越来越大,并且由于该地区属于风蚀地貌,地表易破坏,风蚀作用下导致巷道表面裂隙多,漏风严重,自然发火情况严重,因此亟需对该采空区进行防灭火工作设计。此次现场测定使用束管对110503回采工作面进行监测,按照煤自然发火临界氧浓度指标来划分自燃“三带”区域,同时计算工作面的最小安全推进速度,为工作面安全开采提供了数据支持。根据该矿巷道裂隙多发的状况,使用一种新型封堵材料,进行喷涂,效果良好。据此提出了相应的综合防灭火措施,为该煤矿的自燃防治提出了解决方案,该研究结果有望为相似地貌的煤矿环境提供防灭火借鉴。Xinjiang Yushuling 110503 mining face belongs to class II spontaneous combustion coal seam.With the increase of mining depth,the risk of spontaneous combustion in the goaf of the working face is increasing.Because the area belongs to the wind erosion landform,the surface is easy to be destroyed.Under the action of wind erosion,there are many cracks on the surface of the roadway,the air leakage is serious,and the spontaneous combustion is serious.Therefore,it is urgent to design the fire prevention and extinguishing work in the goaf.In this field test,the beam tube was used to monitor the 110503 working face,and the spontaneous combustion'three zones'area was divided according to the critical oxygen concentration index of coal spontaneous combustion,and the minimum safe advancing speed of the working face was calculated,which provided data support for the safe mining of the working face.According to the condition of multiple cracks in the mine roadway,a new type of plugging material was used for spraying,and the effect was good.Based on this,the corresponding comprehensive fire prevention and extinguishing measures are put forward,which provides a solution for the spontaneous combustion prevention and control of the coal mine.The research results are expected to provide fire prevention and extinguishing reference for coal mine environment with similar landforms.
