摘要
针对深部岩体开采中岩爆日益频发的现象,从岩爆事故发生的现实生产角度提出运用FAT-LPC法对深部开采岩爆事故可能发生的整个过程进行系统分析,分别利用FAT法和改进LEC法(即LPC法)依次递进对所有影响因素和主要因素进行定性、定量分析,综合找出诱发岩爆发生的最主要原因,并提出相应的预防措施,为实际深部开采防治岩爆发生提供一定的科学依据.
In view of the increasingly frequent phenomenon about rock burst in deep rock mass, we put forward FAT-LPC method to analyze the whole process of rock burst accident about the actual production of rock likely path from the macroscopic angle of rock burst accident. And we used FAT method and modified LEC method to analyze qualitatively all the factors and main factor quantitative analysis successively, in order to find out the essential reason about the occurrence of rock burst comprehensively, then put forward the corresponding prevention measures for providing the scientific basis to prevent rock burst in deep mining.
