与煤层自身条件相近但煤层顶底板相对较好的矿井相比,软底软顶煤层的突出危险性在一定程度上有较大增强,这给矿井防治煤与瓦斯突出工作带来了更大的困难。本文对软顶软底煤层掘进防突技术进行了探讨,指出应将消突措施、巷道断面、支护工艺等各方面因素进行综合考虑,以达到较好的消突效果,从而保障软底软顶突出煤层巷道安全快速掘进。 Compared with the mine with similar conditions of the coal seam itself, but the top and bottom of the coal seam is relatively good, the prominent danger of the soft-bottom soft-top coal seam is greatly enhanced to a certain extent, which brings greater pressure to mine prevention and control of coal and gas outburst difficult. In this paper, the research on the technology of outburst prevention in the soft roof with soft bottom is carried out. It is pointed out that all the factors such as elimination measures, roadway cross section and support technology should be considered comprehensively to achieve a better effect of eliminating outbursts, Top Outburst Seam Roadway Safe and Fast Driving.
