摘要
为了评价古城煤矿顶煤的冒放性,提出合理的放煤方式,结合S1301工作面实际地质条件,在分析顶煤冒放性影响因素的基础之上,采用隶属度值法确定各影响因素的隶属度,计算认为古城煤矿3号煤层顶煤冒放性好,现场应采用一刀一放,分段多轮顺序放煤法,保障了矿井高产高效生产。
In order to provide reasonable suggestions for the coal mining method of No.3 coal seam in Gucheng Coal Mine,combined with the actual geological conditions of the working face of S1301, the analysis of the membership degree method showed that the No. 3 coal seam of Gucheng Mine with good caving property, and it was easy to adopt fully mechanized top coal mining, and a reasonable way of coal mining was put forward.
