浅埋近距离煤层群工作面运输顺槽支护方案FLAC模拟
FLAC simulation on support of haulage in shallow-buried short distance coal seams work face
摘要
Abstract
The main mining coal seams 2#,4# of a coal mine in north Shaanxi are shallow-buried short distance coal seams. The 1402 haulage gate needs maintenance support in order to meet the production requirement. Affected by the goaf of 2 coal seam,roof caving has partially appeared in the roadway,and this made the supporting work difficult. Applying FLAC simulation software, this paper established relevant calculating model, analyzed the stress change caused by the mining of contiguous seams, and obtained the deformation law of the haulage gate surrounding rocks in the short distance seam with application of combined support with anchor and joist. The field tests showed that;this maintenance supporting scheme is feasible and it ensured haulage gate roadway' s surrounding rocks stability,met the requirements of safety production. The technology of combined support with anchor and I-joist proposed in this paper has reference value to similar project.关键词
