煤矸石堆场自燃危险性综合评价研究与应用
Study and Application of Comprehensive Evaluation for Spontaneous Combustion Risk in Coal Gangue Dumps
摘要
Abstract
Accompanying with the increasing of coal production,coal gangue dumps(from now on referred to as"dumps")have been increased continuously,and the destruction of the terrain and landscape of the storage yard area have been aggravatied.Due to the toxic and harmful gases and high temperatures genera-ted by the spontaneous combustion of coal gangue,the damage to the surface ecological environment,and a huge safety threaten to the biodiversity and development and utilization of the storage yard will be caused.In this paper,by using satellite remote sensing time series monitoring,surface investigation,harmful gas monitoring,and shallow ground temperature detection methods,the risk assessment of spon-taneous combustion in storage yards has been carried out.A method for evaluating the risk of spontaneous combustion in storage yards has been put forward.A hazardous gas hazard assessment method based on concentration combined with toxicity hazard index to determine weights,a shallow ground temperature clustering analysis method to judge ground temperature anomalies,and a CRITIC weighted comprehensive evaluation method for yard self ignition hazard based on three primary indicators of hazardous gas,self ig-nition development risk,and self ignition disaster hazard degree have been put forward.It is showed that by adjusting the deployment of the yard development and utilization plan,comprehensive evaluation of the risk level of spontaneous combustion in the yard can be effectively reduced.It will provide some references for the prevention and control of spontaneous combustion disasters in coal gangue yards and sustainable de-velopment and utilization.关键词
