露天煤矿排土场矸石自燃治理方案研究及实践OA

In order to solve the complex environmental problems of air pollution,water pollution,and soil degradation caused by the spontaneous combustion of coal gangue in the south dump of Pingshuo Antaibao Open-pit Mine,based on the investigation of the current environmental status of the dump and analysis of fire characteristics,this article proposes a full chain control technology system based on"temperature dynamic monitoring-fire extinguishing and reignition prevention-slope shaping and drainage interception-ecological restoration".According to the distribution characteristics of the fire area and the degree of environmental risk,the research area is divided into six differentiated control units,and comprehensive control is implemented in stages and zones based on the engineering verification results of the experimental area.The results show that the spontaneous combustion of coal gangue is effectively controlled after control,the stability of the slope is significantly improved,the vegetation coverage rate is significantly increased,and the ecological environment quality continues to improve.
