滕南矿区矿井水灾害链及断链减灾研究

Study on Mine Water Hazard Chains and Chain- cutting Disaster Mitigation in Tengnan Mining Area

针对我国煤矿开采矿井水害频发现象,运用灾害链理论研究滕南矿区矿井水灾害链作用机理,提出孕育断链减灾方法。综合分析滕南矿区水文地质条件及矿井水灾变特点,发现矿井水灾害链发育3个阶段,即灾害孕育阶段、潜存阶段、诱发阶段。通过对矿井水灾害链式作用机理研究,发现滕南矿区是由原生灾害、次生灾害、派生灾害组成的复杂灾害链系统。运用层次分析方法分析矿井突水影响因子权重并对矿井水灾害性分区,采取时间序列分析不同工作面涌水量,从而判断矿井水灾害链发育阶段,提出孕源断链减灾措施。

In this article, for the phenomenon of water bursting occurring frequently in China mine, disaster chain theory is used to study the mechanism of mine water disaster chain in Tengnan Mining area, the paper proposed the nascent stage chain - cutting meth- od. Firstly, comprehensively analyzing the hydrogeological conditions in Tengnan Mine and the characteristics of mine water hazard, it found three stages development of the mine water disaster chain including the disaster nascent stage, latent stage, and erupting stage. Then, by studying mechanism of mine water disaster chain in Tengnan Mine,former disasters, secondary disasters and derived complex disasters are found. At last, the hierarchical analysis method is used to analyze the weight of mine water disaster impacting factor and mine waler disaster is partitioned as well. What＇s more, the study takes the time series to analyze the water yield in different working face in order to determine the developmental stage of the mine water disaster chain and finally provides the measure of nascent stage chain - cutting.
