摘要
针对新景矿8123综放工作面开采煤层厚、近邻层漏风严重以及遗煤自燃情况复杂等问题,采取柬管监测,明确了采空区自燃"三带"的分布范围,并计算得出工作面的最小推进速度,确保工作面安全回采,可为矿井地质条件相类似采空区遗煤自燃防控提供参考.
Abstract
In response to the problems of thick coal seams,severe air leakage in adjacent layers,and complex spontaneous combustion of residual coal in the 8123 fully mechanized caving face of Xinjing Mine,bundle tube monitoring was adopted to clarify the distribution range of the"three zones"of spontaneous combustion in goaf,and the minimum advancing speed of the working face was calculated to ensure safe mining.This can provide reference for the prevention and control of spontaneous combustion of residual coal in goaf areas with similar geological conditions in the mine.
