新阳井田矿井突水灰色风险性评价研究

Grey-risk Assessment of Water Inrush in Xinyang Mine

为了研究山西新阳井田上组煤顶板及下组煤底板突水水害问题,通过统计分析以往井田内突水实例,采用风险率和风险度评价与灰色评价理论相结合的方法建立统计学模型,对上组煤顶板及下组煤底板的突水风险率和突水风险度进行预测评价,评价结果表明井田下组煤发生底板突水的风险大于上组煤发生顶板突水的风险。

The water inrush of the roof of upper coal group and the floor of lower coal group in Xinyang was studied.By statistic analysis on previous water inrush cases,risk rate and degree evaluation and grey evaluation were combined to establish a statistic model,which was used to predict and assess the water inrush risk rate and degree of the roof of the upper group and the floor of the lower group.The evaluation showed that the floor water inrush risk was larger than the roof water inrush risk.
