摘要
为提高薄煤层资源采出率和开采效率,采用理论分析和工业试验的方法,在薄煤层工作面开采实践的基础上,对薄煤层自动化工作面开采设备选型进行研究,研制了适应于薄煤层的综采液压支架、采煤机和刮板输送机,并进行工作面自动化平台建设,增设视频监控功能,提高了工作面自动化水平,并在黄沙煤矿进行了工业试验,实现煤层厚度0.75m自动化开采,试验工作面月产达3.67万t,矿井煤炭采出率提高了4%,延长矿井服务年限5年。
In order to improve the resource mining rate of the thin seam and the mining efficiency, based on the practices on the mining in the thin seam coal mining face, the theoretical analysis and the industrial trial were applied to study the mining equipment selection for the automatic coal mining face in thin seam. The hydraulic powered support, coal shearer and scrape conveyer suitable for the fully mechanized mining in thin seam were researched and manufactured.With the automatic platform of the coal mining face established with the video mo- nitoring and control functions, the automatic level of the coal mining face was improved.A industrial trial was conducted in Huangsha Mine, an automatic mining in a thin seam with a thickness of 0.75 m was realized.The month production of the trial face was 36,700 t.The coal mining rate of the mine was increased by 4% and the mine service life was ccteded by five years.
