摘要
为解决山西焦煤集团屯兰矿目前使用的突出敏感指标及其临界值与矿井实际突出危险性不一致的问题,通过突出模拟实验,研究煤体突出与瓦斯含量P和瓦斯压力W的关系,通过对实验数据的分析整理初步确定,瓦斯压力预测临界值位于0.727 MPa附近,瓦斯含量预测临界值为7.689 m^3/t附近,通过Fish准测的线性判别法,判定2号煤层区域预测临界值为瓦斯压力0.728 MPa,瓦斯含量为7.665 m^3/t,理论分析计算得到2号煤层区域预测指标的敏感序列为W>P。研究成果对于该矿区域瓦斯突出危险性预测具有重要的意义。
In order to solve the problem of inconsistency between the prominence sensitive index and the actual prominence hazard of Tunlan Mine,the relationship between prominence,gas content and gas pressure was investigated through prominence simulation experiment,and the predicted critical value of gas pressure was about 0.727 MPa and gas content around 7.689 m^3/t.According to the linear discrimination method of Fish quasi-test,the critical value of No.2 coal seam region prediction was 0.728 MPa of gas pressure,and the gas content 7.665 m^3/t.Based on theoretical analysis and calculation,the sensitive sequence of No.2 coal seam region prediction index was W>P.The research results were of great significance for the prediction of gas outburst risk in Tunlan Mine.
