高地温超长综放工作面煤自燃防治技术

摘要

该文以某矿井2301S综采放顶煤工作面为例，揭示了高地温环境对煤自燃特性的影响，归纳了超长综放工作面煤自燃特点，确定了采空区自燃“三带”及危险区域，计算了最低安全推进度，建立了高地温超长综放工作面煤自燃防治技术体系。%This paper, taking a 2301S mine fully mechanized top coal caving working face as an example, revealed the effect of high temperature environment on the coal combustion characteristic, summarized the coal spontaneous combustion characteristics of the super long fully mechanized caving working face, determined the coal spontaneous"three zone"of gob and the danger zone, calculated the minimum safety mining schedule, and established a coal spontaneous combustion control technology system in the high temperature and super long fully mechanized top coal caving working face.
