全苏矿山测量科学研究所在顿巴斯所属各矿井揭开突出危险煤层时,对消除煤与瓦斯突出方法进行了研究和工业性试验。该方法建立的目的是在于揭开煤层时,为快速抑制由于放炮激发的突出冲击波创造条件。为此,要在开拓的有限范围的巷道内建筑堵塞隔墙。根据采用限制突出方法揭开突出危险煤层完成的矿井试验表明,虽然堵塞隔墙的结构是可靠的,但它有一系列的缺点。
The Institute of Surveying and Measurement of All-China Institute of Minerals and Metallurgy conducted a study and industrial test on eliminating coal and gas outburst when uncovering dangerous coal seams in all the mines belonging to Donbass. The purpose of this method is to create the conditions for rapidly suppressing the salient shock wave excited by the blasting when uncovering the coal seam. To this end, in a pioneering development of a limited range of road blocking block wall. According to a well test conducted using a well-defined method to highlight the most dangerous coal seams, it shows that although the blockage wall structure is reliable, it has a number of drawbacks.
