摘要
为构建中厚煤层超长工作面“三机”设备的高效配套体系,以小保当二号煤矿132202工作面为工程背景,综合考虑2~3 m煤层赋存条件与综采工艺要求,提出适用于450 m超长工作面的千万吨级机械化开采配套方案。通过对采煤机、刮板输送机、液压支架的功率匹配性、运输能力及空间尺寸等参数进行系统性核算,确定了设备选型方案。井下运行结果表明:该配套方案合理,设备运行稳定性良好,实现了年产千万吨的预期目标。该配套方案为相似地质条件下中厚煤层超长工作面的机械化开采提供了参数设计依据与工程实践经验,对推动超长工作面开采技术的推广应用具有重要参考价值。
To provide a more reasonable and feasible“three-machine”matching scheme for ultra-long working faces in medium-thick coal seams,we proposed a matching scheme for a 450 m ultra-long fully mechanized working face at the 132202 working face in Xiaobaodang No.2 Mine,considering the geological conditions and mining processes for the 2~3 m medium-thick coal seam.The matching scheme was determined through systematically calculating the parameters such as the power matching of coal shearers,scraper conveyors and hydraulic supports,as well as the transportation capacity and dimensions of the installation space.Underground operation results showed that,the matching scheme was reasonable,the equipment operated well,and the expected productivity(ten million tons per year)was achieved.This matching scheme provided both theoretical and practical experience for achieving mechanized mining of ultra-long working faces in medium-thick coal seams under similar conditions and contributes to the further development of ultra-long working face applications.
