摘    要:通过对耿村矿13011综放面采空区“三带”的观测,证实了在采空区中部布置观测管路观测气体方案的可行性,采集的气体更具代表性.在分析观测数据的基础上确定了采空区“三带”的宽度范围,并结合耿村矿煤层自然发火期,指出了防止采空区遗煤自燃所必需的工作面最低推进速度,讨论了某一工作面在不同时期影响“三带”范围变化的主要因素,为防止采空区遗煤自燃提供了依据.

关 键 词:综放面  采空区  三带

Abstract:By measuring the “three zones” in the goaf of fully_mechanized at working face 13011, Gengcun mine, the author verified that it is feasible to lay out a set of measuring pipes for collecting gases in the middle of the goaf. On the basis of analysis of the collected data, the ranges of “three zones” are determined. Considering the period of catching fire naturaly of coal seam of Gengcun mine, the cowest advancing speed which is cast permitted to prevent coal rest in the goaf catching fire is given and the major factors that determine the ranges of “three zones” for a coal mine in different time are discussed. Thus it has provided some scientific proof to prevent coal spantenous combustion in a goaf.
Keywords:fully_mechamized working face  goaf  three zones
