摘要
针对大阳煤矿井田内3号煤层优质资源已濒临枯竭,在全部开采完结再进行新的煤层资源开发,难以保证矿井的正常接续和生产衔接,影响矿井的后续经营与可持续发展等问题,对大阳煤矿3号、15号可采煤层进行了研究分析,提出了“中厚-厚煤层、高-低硫分、高-低热量”的配采方案。通过线性规划理论,使用二元一次方程组的联合求解方式计算得出最佳配采比例,确定了3、15号煤层2:1的配采方案。方案确定后,利用井下原有生产系统,新建一处西回风立井开采,并对运输设备进行了选择,实现了高热量、低硫分的配煤生产,具有更优的经济价值,在保证矿井1.80 Mt/a稳定生产的同时,延长了矿井服务年限。
Aiming at the problems that the high-quality resources of the No.3 coal seam within the well field in Dayang Coal Mine are on the brink of depletion,and it is difficult to ensure the normal continuity and production connection of the mine before carrying out new coal seam resource development after all mining is completed,which affects the subsequent operation and sustainable development of the mine,etc,research and analysis are conducted on the No.3 and No.15 minable coal seams in Dayang Coal Mine.A matching mining scheme of"thin-thick coal seam,high-low sulfur content,high-low heat"is proposed,and through linear programming theory,the optimal mining ratio is calculated by using a joint solution method of binary linear equation group,and the 2:1 matching mining scheme for No.3 and No.15 coal seams is determined.After the scheme is determined,a new west return air shaft is constructed using the underground original production system,and transportation equipment is selected to achieve high heat and low sulfur content coal blending production,which has better economic value.While ensuring stable production of 1.80 Mt/a in the mine,the service length of the mine is extended.
