在顿巴斯,揭开煤层之前,通过测量煤层中的瓦斯压力值来检查煤体瓦斯动力状态的变化情况。同时,按包括瓦斯压力在内的综合指标预测揭煤地点的突出危险性。这种方法要求,预测突出危险性时应考虑那些反映形成突出危险性必要和充分条件的指标,而在检查执行措施效果时,应考虑那些仅反映发生煤与瓦斯突出必要条件的指标。
Before the start of the coal seam in Donbass, the gas pressure in the coal seam was measured to check the gas dynamics in the coal seam. At the same time, according to comprehensive indicators including gas pressure to predict the outstanding risk of exposing location. This approach requires that projections that highlight salient risks should take into account those indicators that reflect the necessary and sufficient conditions for salient dangers, and that indicators that reflect only the conditions necessary for the occurrence of coal and gas outbursts should be considered when examining the effects of enforcement measures.
