【摘要】 提出了高硫矿山“高温采场”的概念。用热力学原理解释了含硫矿石氧化和自燃所释放出的大量热量的积聚是致使采场温度升高的主要原因。分析了高硫矿山高温采场产生的主要危害,如引发硫尘爆、造成围岩失稳和环境污染等。最后阐述了主要的防治措施,如保持采场通风良好、及时出矿、矿石块度适宜、注浆锚索支护等。更多还原

【Abstract】 This thesis presents the new concept of "high-temperature stope" in high-sulphur mines,explains by the principle of heat mechanics that it is formed due to the accumulation of large quantities of heat generated by the oxidation and spontaneous combustion of high-sulphur ore,analyzes main harms of high-temperature stope such as causing sulphur-dust explosion,instable surrounding rock and environmental pollution,and finally expounds the main measures of prevention and treatment against high-temperature stope such as good ventilation,timely ore drawing,appropriate ore size and grouted cable supporting.更多还原
