介绍了瑞克充填材料的基本性能和充填密闭墙的优点,将该材料在柴沟煤矿1501采煤工作面辅运巷、皮带巷进行充填密闭墙的应用后,对1501采煤工作面起到了良好的密闭作用:辅运巷密闭墙内的O2体积分数由20%左右降到了2%左右,皮带巷密闭墙内的O2体积分数由18%左右下降到了2%左右,且两密闭墙内均未检测到乙烯、乙炔等煤自然发火标志性气体,因此,可以判断在停产期间此次密闭消除了1501采煤工作面煤自燃倾向性。
This paper introduces the basic performance of Rick packing material and the advantages of filling the confined wall. After the application of this material to the confinement wall of 1501 coal mining face in Chaigou coal mine and the belt lane, the 1501 coal face is played Good confinement effect: The volume fraction of O2 in the confining wall of auxiliary transport lane decreased from about 20% to about 2%, and the volume fraction of O2 in the confined wall of belt lane dropped from about 18% to about 2% No detectable natural gas flammable gases such as ethylene and acetylene were found. Therefore, it can be judged that the propensity to spontaneous combustion of coal at 1501 coalface was eliminated during the shutdown.
