Qualitative and quantitative evaluation of impact risk in underground mine

冲击危险性评价是将冲击地压抽象的能量本质具象化的关键环节,对于冲击地压有效防控有着直接的支撑作用。笔者梳理了冲击危险性评价的基本概念和功能定位,指出冲击危险性评价天然具有多尺度的属性,各尺度评价应相互兼容、逐级支撑,并对目前冲击危险性评价中指标间关联不足、危险区域划分偏主观、对于多要素和大数据的兼容性有限,以及评价工作趋于刻板等问题进行了剖析,为此,基于广义“三因素”理论,提出冲击危险性定性评价应兼顾“要素齐备”和“逻辑齐备”的原则,并基于“矿井自身数据,指导矿井自身生产”的原则给出了冲击危险性定量评价的基本方法,为解决冲击危险性评价现存问题做出了探索,明确了冲击危险性评价的后续攻关方向。
Impact risk assessment is the key link to concretize the abstract energy essence of coal bump,which has a direct supporting role for the effective prevention and control of coal bump. This paper combs the basic concept and function orientation of impact risk assessment and points out that impact risk assessment naturally has multi-scale attributes,each scale assessment should be compatible with each other and support step by step. In view of the current impact risk assessment,the problems including insufficient correlation between indicators,subjective division of risk areas,limited compatibility for multi elements and big data,and the stereotype trend of assessment work are analyzed. Therefore,based on the generalized“three factors” theory,it is proposed that the qualitative evaluation of impact risk should take into account the principle of“complete elements” and“complete logic”,and the basic method of quantitative evaluation of impact risk based on the principle of“mine‘s own production guided by its own data”. This paper makes an exploration to solve the existing problems of impact risk assessment,and provides support for the clear direction of the follow-up research.
