赵楼煤矿高温热害防治研究与实践

结合兖州赵楼煤矿高温热害防治研究与实践，对开拓、掘进、回采工作面热源状况进行分析，从矿井建设到投产不同阶段的高温热害防治措施进行研究。研究表明，赵楼煤矿开拓及掘进工作面以围岩散热为主，采煤工作面以机电设备及热水散热为主；赵楼煤矿从矿井设计、降温设备、管理措施、个人防护等多方面综合考虑，采取矿井分区通风、机械降温、工作面采用下行通风、缩减职工作业时间、补充盐水等方法对矿井建设到矿井投产的高温热害进行全过程、全方位的综合防治，其中在矿井建设时期、矿井建设过渡时期采用“地面制冷站-井口风室喷水冷风制备-井下通风工作面降温/矿井通风系统井下降温”制冷工艺，矿井投产后采取在井底车场设置制冷硐室进行井下集中制冷，均取得良好的降温效果。

Research and application on preventive measures against heat disaster in Zhaolou Coal Mine

Based on the characteristics of Zhaolou Coal Mine,analyzed the condition of heat sources at open face,heading face and stope face,and also studied the prevention and control measures against the heat disaster from mine construction to mine production in Zhaolou Coal Mine.The research shows that the open face and heading face are mainly in wall rock radiating,coal face is mainly in electrical equipment and hot water radiating.Considering from mining design,radiation equipment,operating method and personal protection,Zhaolou Coal Mine used all possible ways such as separate ventilation,mechanical radiation,descensional ventilation,reducing working time and make up brine to control the heat disaster from mine construction to mine production.During the coal mine construction period and transitional period,Zhaolou Coal Mine used some refrigeration technology,such as “ground cooling station spray equipment to cool wind in mine plenum cooling the ventilation face/ventilation system” and set up a cooling chamber at the parking place of underground mine to centralized refrigeration.All of these get a good cooling result.
