【摘要】：薄煤层开采效率受多种因素影响,以大斗沟煤矿薄煤层开采为基础,应用计算机模拟技术,将现场调研的停开机时间、采煤机速度及工艺参数作为模拟的基础数据,再现工作面生产过程,详细的分析了各影响因素对工作面开采效率的影响,发现了工作面生产系统存在的问题。模拟分析表明:生产设备因素和辅助设备因素是影响大斗沟煤矿82203工作面开采效率的最主要因素,82203工作面在地质条件和开采水平处于国内平均水平时,年产量可以达到58.4万t。模拟结果为提高薄煤层的开采效率,优化薄煤层工作面的生产环节提供了依据。
[Abstract]:The mining efficiency of thin coal seam is affected by many factors. Based on the mining of thin coal seam in Dadougou coal mine, using computer simulation technology, the time of stopping machine, the speed of shearer and the technological parameters of field investigation are taken as the basic data of simulation. The production process of the working face is reproduced and the influence factors on the mining efficiency of the working face are analyzed in detail. The problems in the production system of the working face are found. The simulation analysis shows that the factors of production equipment and auxiliary equipment are the most important factors affecting the mining efficiency of No. 82203 face in Dadougou Coal Mine. When the geological conditions and mining level are at the domestic average level, the annual output can reach 584000 tons. The simulation results provide the basis for improving the mining efficiency of thin coal seam and optimizing the production link of thin coal seam working face.
