摘要
通过对钱家营矿地质构造、瓦斯含量、瓦斯压力、煤厚变异特性、煤的结构特性、顶底板岩性等相关突出因素的综合分析,确定地质构造关键因素的突出临界值为0.308。并依据相关突出因素的监测值和临界值确定了预警指标瓦斯含量的修正值M,最终运用MATLAB软件和回归理论,以4 m3/min为瓦斯涌出量的临界值构建钱家营矿突出预警系统,实现突出预警可视化操作。
Through comprehensive analysis on several prominent factors in Qianjiaying Mine, factors including geological struc- ture, gas content, gas pressure, change of coal thickness, characteristics of coal structure as well as lithology of roof and floor, the prominent critical value of geological structure was determined as 0.308. According to the monitoring value and the critical value of related prominent factors, the corrected value M of the early warning index for gas content was determined. Finally, the early warning system with 4 m3/min as the critical value of gas emission was constructed by MATLAB and regression theo- ry, which realized the visualized operation of outburst warning.
