浅谈海州露天矿残煤自燃治理措施

Introduction to haizhou open-pit coal mine the coal spontaneous combustion control measures

由于海州露天矿边坡岩体不断滑坡,形成了小井巷道的通风风路,同时,残煤自燃使周边岩层软化或空化,造成边坡的滑塌现象时有发生,形成恶性循环。本文采用粉煤灰注浆,通过分析海州露天矿边坡残煤自燃的成因和特征,结合工程实际,得出一种有效的露天矿边坡残煤自燃治理措施。

Haizhou open-pit coal mine slope rock mass landslide constantly,form the little well is a wind tunnel ventilation road,at the same time,the residual coal spontaneous combustion make surrounding rock softening or cavitation,slope sliding phenomenon occurs frequently,a vicious cycle.In this paper,using fly ash grouting,through analyzing the cause of haizhou openpit coal mine slope residual coal spontaneous combustion and characteristics,combined with the engineering practice,it is concluded that an effective slope residual coal spontaneous combustion control measures.
