摘要
煤矿智能化的发展为提升矿井安全保障能力提供了新的思路,但在煤矿灾害的感知方法研究上仍有不足,难以对灾害发育的阶段进行有效感知,缺少针对灾害发育不同阶段的防治措施.针对上述问题,本文提出了一种基于灾害演化特征分析的煤矿灾害感知方法,通过研究矿井灾害发育机制,划分灾害的演化阶段,提取阶段的转化条件并识别控制因素,结合关联性分析方法,选择敏感控制因素进行灾害发育的阶段感知.以煤矿断层活化突水事故为例,进行了灾害感知方法的试验验证,结果表明,敏感控制因素随工作面推进的变化能够反映断层活化突水事故演化程度,因此,基于演化特征分析的感知方法有望为煤矿灾害发育阶段感知提供参考.
Abstract
The development of coal mine intelligence provides new perspectives for enhancing mine safety assurance capabilities.However,research on the perception method of coal mine disasters is still insufficient,and it is difficult to effectively perceive the stage of disaster development,and then the prevention and control measures taken are not targeted to the stage of disaster development.To address these issues,this paper proposes a coal mine disaster perception method based on the analysis of disaster evolution characteristics.By studying the development mechanism of mine disasters,the evolution stages of disasters are delineated,transition conditions of each stage are identified,and controlling factors are recognized.Combining correlation analysis methods,sensitive indicators are selected for perceiving the stages of disaster development.Using the coal mine water inrush accident triggered by fault activation as an example,experimental verification of the disaster perception method is conducted.The results indicate that sensitive characteristics reflecting the degree of evolution of the fault activation water inrush accident vary with the advancement of the working face.Therefore,perception methods based on evolutionary feature analysis hold promise for providing reference for perceiving the stages of coal mine disaster development.
