淮北煤矿事故与气象条件的分析研究
|
摘要
利用气象地面观测资料和高空探测资料及淮北煤矿事故的相关资料,应用数理统计方法,分析淮北煤矿事故的时空分布特征,。结果表明:煤矿事故在全年各月均可出现;在气象要素存在地面气压下降,气温回升,湿度<30%的气象条件下煤矿事故较易发生;经过对井下气象条件的试验分析证明;温度过高过低,湿度较小,当井下风速<0.5m.s-1时,工伤事故较易发生;瓦斯事故一般出现在地面有冷锋过境、700hPa受西北气流控制、850hPa处于暖温度区的大尺度环流背景下。
Based on meteorological data and information related Huaibei coal mine accidents,using mathematical statistical methods,temporal and spatial distribution characteristics of the accident were analyzed.The results show that coal mine accidents can occur in each month throughout the year.With surface pressure decreasing,the temperature rising,humidity <30%,it is more prone to mine accidents.Then the test of underground weather conditions showed with too high or low temperature,low humidity,the underground wind speed <0.5ms-1(700hPa airflow controlled by the Northwest,the large-scale circulation of 850hPa controlled by warm temperature),it is more prone to casualty(gas accidents).
