煤炭是我国的第一能源,在一次性能源结构中约占70%以上。但是,由于开采条件的复杂性,使得矿山瓦斯、煤尘、水、火、顶底板事故的隐患无处不在。在已发生的重大事故中,瓦斯煤尘爆炸占了绝大多数。在这些瓦斯事故中,绝大部分是由于通风不良造成局部瓦斯积聚,再遇上由于各种不同原因引起的火花,从而引起瓦斯或瓦斯煤尘爆炸。因此,本文对煤矿矿井通风安全控制中的影响因素的分析具有一定的意义。一、概述矿井通风是矿井安全工作的基础,是稀释和排除矿井瓦斯与
Coal is the primary energy source in China, accounting for over 70% of the disposable energy structure. However, due to the complexity of mining conditions, the hidden dangers of mine gas, coal dust, water, fire and roof and floor accidents are ubiquitous. In the major accidents that have occurred, gas and coal dust explosion accounted for the vast majority. In these gas accidents, most of them are due to poor ventilation caused by local gas accumulation, and then due to various causes of sparks, resulting in gas or gas coal dust explosion. Therefore, this article is of great significance to the analysis of the influential factors in the mine ventilation safety control in coal mines. First, an overview Mine ventilation is the basis for mine safety work, is to dilute and exclude mine gas and
