摘要
针对目前突出参数测定存在不考虑湿度的问题,通过理论分析和实验室实验研究得到随着无烟煤煤体内水分的增大,坚固性系数f也随之增大,对f值的影响误差甚至可达到35.41%,甚至使小于临界值0.5的突出煤层的测定值增加为大于临界值的非突出煤。
Considering the problem that the existing indices measurement didn′ t think over humidity,according to theoretical analysis and experimental study, got the result that with the increasing of water,the robustness coefficient f increased, the effect of f value error can be achieved even 35.41%, even less than the critical value of 0.5 measured increasing in outburst coal seam was greater than the critical value of non outburst coal.
