山西煤矿瓦斯爆炸与昆仑山口西8.1级地震关系的研究

A Study on Relation between Gas Explosion at Coal Mines of Shanxi Province and West Kunlun Mountain Col Earthquake of M8.1

根据收集到的山西省部分煤矿1997年至2002年9月的瓦斯记录资料及山西省地震活动性和前兆观测的资料,对山西2001年11月一系列特大瓦斯爆炸事故与2001年11月14日新疆、青海交界发生的昆仑山口西8.1级大地震的关系进行了分析研究。认为,从现有资料分析,瓦斯爆炸与昆仑山口西8.1级大地震以及近年来山西及附近地区的中强地震不存在旬或月尺度的相关关系,但可能存在震前与震后几小时和几天尺度的相关性。

Based on the gas data from 1997 to Sep.2002, collected from some of coal mines of Shanxi province, and the seismicity and precursor observation data of Shanxi province, the relation between a series of gas explosions at coal mines of Shanxi province during Nov.,2001 and Nov. 14,2001 west Kunlun Mountain col Earthquake of 8.1 at the boundary area of Xinjiang and Qinghai is studied. The results show that there is no correlation between gas explosion and great west Kunlun Mountain col Earthquake of 8.1 as well as the mediumstrong earthquakes,occurred in Shanxi and its adjacent regions, in scale of month or tenday,but probably correlative several hours or days before the earthquake.
