摘要
工作面推进速度直接影响采空区自然发火的严重程度。为了准确定量确定采空区自然发火防治措施技术参数,以同忻矿8101工作面为例,利用数值模拟软件分别计算当推进速度为1.2m/d、1.4m/d、1.6m/d、2.4m/d、4m/d、5.6m/d和8m/d时采空区内气体和冒落矸石温度场的时空分布情况,确定了工作面最小推进速度,以指导现场安全生产。
The work face advancing speed directly affects the severity of spontaneous combustion in the gob. In order to quantitatively determine the technical parameters of spontaneous combustion control measures in the gob, taking the 8101 work face of Tongxin Mine as example, the numerical simulation software was used to calculate the temperature field distribution of gas and caved gangue in the gob when the advancing speed was 1.2 m/d, 1.4 m/d, 1.6 m/d, 2.4 m/d, 4 m/d, 5.6 m/d and 8 m/ d respectively, the minimum advancing speed was determined and the in-situ safety production was instructed.
