浅析矿井瓦斯爆炸事故的危险度评价

在井下煤炭开采过程中,易燃易爆气体瓦斯危害始终存在,而瓦斯爆炸事故一旦发生,一般会造成灾难性的后果。因此预防瓦斯事故是十分关键和重要的,应用危险度评价法,通过对瓦斯的相关各指标的分别赋值,根据各指标量与瓦斯的危险度的关系,得出瓦斯危险度,再依据危险度的分级情况,就可以对矿井瓦斯安全状况作出评价分析和提出合理的安全对策措施及建议。

to simple analyze dangerous degree appraisement of damp explosion accident in mine

When mining coal in mine, danger of inflammable explosive damp exists all along, once damp explosion accident occur, normally, it can cause disastrous consequence. Damp accidents is very key with important present. We apply dangerous degree evaluation, through the relation each index for damp assignment and basis are each the dangerous degree of index quantity and damp relation, reach damp dangerous degree. From dangerous degree grade condition, we can make appraisement analysis for mine safe situation and put forward reasonable safe countermeasure measure and suggestion.
