摘要
为了解永川煤矿高温热害的形成原因,通过定性分析和定量计算,对矿井各种热源进行分析和计算,得到各种热源散热的量化指标,从而判断各种热源对矿井高温热害的影响程度。结果表明:围岩散热在矿井进风流线路上的所有热源散热中约占60%,而在采掘工作面热源散热中约占64%。围岩散热和机电设备散热约占采掘工作面总热源的80%,是造成矿井高温热害的主要原因,矿井高温热害的治理途径提供了理论依据。
In order to ascertain the formation causes of high temperature heat hazard in Yongchuan Colliery, after qualitative analysis and quantitative calculation, various heat sources in the mine were analyzed and calculated, and the quantitative cooling indexes of various heat sources were obtained, so as to judge the influence degree of various heat sources on high temperature heat hazard in the mine. The results showed: the heat dissipation of surrounding rocks accounted for about 60% of the total heat dissipation of all heat sources in air intake line, and accounted for about 64% of the heat dissipation of heat sources on mining face. The heat dissipation of surrounding rocks and electromechanical equipments accounted for about 80% of total heat sources on mining face, which was the main cause of high temperature heat hazard, which offered theoretical reference for the treatment of high temperature heat hazard in the mine.
