在煤矿地下开采过程中,存在着发生危及人身安全和损失国家财产的事故的危险.在每一次发生事故的区域,必然有许多产生事故的外因现象表现出来.事故的发生正是由于这些外因达到了某种特定的形式.本文以矿井自然发火事故为例,探讨以概率回归的方法,在统计过去历次不同等级事故发生的基础上,得出发生不同等级事故的概率回归方程.应用这个概率回归方程,对于采场任一局部区域,根据其外因条件预测该区域发生自然发火事故的危险程度.
In underground coal mining, there is the danger of accidents that endanger personal safety and the loss of state property, and in the event of an accident, there are bound to be a number of external causes of accidents that manifest themselves precisely because of these external causes A certain specific form.In this paper, the spontaneous combustion accidents in mines as an example, to explore the probability of regression method, statistics in the past on the basis of different levels of accidents, the probability of occurrence of different levels of accident probability regression equation. Using this probability regression For any partial area of the stope, the degree of danger of spontaneous fire accidents in this area can be predicted according to its external factors.
