提高工作面设备的工时利用率,可促使其经济效果的提高。在采用高效技术装备的综采工作面,这具有特别重要的意义。据统计:在具有中等复杂矿山地质条件的综采工作面。每停产1小时,就少出60～100吨煤炭;而劳动效率则降低15％。 设备利用系数是以设备运转时间系数来表示。该系数的提高通常采用缩短班内停工时间和非生产作业时间、减少操作中断时间,以及采用采煤与辅助作业同时并进的方法来达到。选择工作面最佳参数和确定回采工作面作业组的合理人数,对在时间上最充分利用设备有着重大的促进作用。除技术、组织因素而外,社会经济因素(采煤队伍的思想素质、精神状态、劳动纪律、运用先进经验及工休时间等)对设备利用系数也具有较大的影响。
Improve working hours utilization of equipment, can promote its economic effect. This is of special significance in the use of fully mechanized mining face equipped with efficient technology. According to statistics: In a medium complex mining geological conditions of fully mechanized mining face. For every one hour of shutdown, 60-100 tons less coal is required, while labor efficiency is reduced by 15%. Equipment utilization factor is based on equipment operating time coefficient. The increase of this coefficient is usually achieved by shortening the time of out-of-class and non-productive work, reducing the time of operation disruption and adopting the method of simultaneous mining and auxiliary work. Choosing the best working face parameters and determining the reasonable number of working faces in a working face make a significant contribution to making the best use of equipment over time. In addition to technical and organizational factors, socio-economic factors (ideological quality of coal mining team, mental status, labor discipline, the use of advanced experience and working hours, etc.) also have a greater impact on equipment utilization factor.
