构造煤层突出危险性预测敏感指标临界值研究

Research on Highlighted Critical Danger to the Sensitive Target Value in the Construction of Coal Seams

基于模糊数学理论,在现场考察和试验模拟的基础上,提出确定预测敏感指标的数值模型,通过数值关系确定目标煤层的敏感指标;针对试验矿井目标煤层,采用"三率"法和模糊聚类法分析了B11-2煤层预测指标的敏感性,得出了目标煤层B11-2突出预测敏感指标为钻屑量S,并测出钻屑量S指标的临界值为6.57 kg/m。

Based on vague mathematics and probability theory and in the field visit and laboratory test simulates on the basis of established forecasts sensitive indicators of the mathematical model,the abstract sensitive issue of specific indicators determine the value to test the target.coal seams intermixed with the "three rate" and vague clustering law analyzed B11-2 coal seams intermixed forecast level of sensitivity,the target coal seams intermixed B11-2 outstanding forecast sensitive to get indicators and what ...
