摘要:
为了避免突出的漏报,提高煤与瓦斯突出预测工作的有效性与准确率,在系统分析煤与瓦斯突出预测敏感指标以及各影响因素对突出的影响程度基础上,以显德汪矿为例提出了基于钻屑量S,Δh2和K1等3种预测指标的综合指标K值,并建立了综合指标的计算公式,实现了对煤与瓦斯突出预测的各项指标的综合考虑。基于该指标对显德汪矿进行了突出预测并确定了临界值。根据所确定的临界值,对分析结果进行验证,证明所选取的临界值符合要求。在此基础上对煤与瓦斯突出预测指标临界值的确定方法进行了推广,建立了具有普遍使用性的矿井瓦斯突出综合预测指标及其临界值确定方法,并提出将该综合预测指标与各单项预测指标结合应用。
Abstract:
In order to avoid missing reports on coal and gas outburst and improve the effectiveness and accuracy of coal and gas outbursts prediction,sensitive indexes of coal and gas outbursts prediction and influence degree on outburst of various influential factors were analyzed.Then the comprehensive index k,which takes Xiandewang coal mine for example,was put forward based on coal powder quantity of bore S,Δh2 and K1 ,and the calculation formula of comprehensive index was established.The comprehensive consideration of the indicators for coal and gas outbursts prediction was realized.Outburst prediction was done for Xiandewang coal mine based on the index,and the related critical value was identified.The analysis results was verified based on the critical value, and it was proved that the critical value meets the requirements.The determination method of prediction index critical value of coal and gas outburst was popularized.Then the determination method of prediction index and its critical value of coal and gas outburst with universal usability were established.At last the combined application of comprehensive index and each individual predictor was put forward.
