| 摘 要： | 武家塔露天煤矿是神东天隆集团有限责任公司的重要煤矿企业,根据企业发展的需要、煤矿地质条件、市场销售条件等,确定该矿合理的生产能力为300万ta,目前设计生产能力为60万ta,采煤工作线长度600m左右,不能满足生产能力扩大的要求。通过确定合理的工作帮水平推进速度,考虑剥离内排运距和端帮剥离量对剥采比的影响等,进行详细地经济分析确定合理的采煤工作线长度。

| Abstract: | Wujiata open-pit coal mine is the main coal enterprise of Shendong tianlong group CO., Ltd , the reasonable throughput is 300×104 ta. according to the needs of enterprise and geological cond-ition and coal sell market. At present , the fact throughput is 60×104 ta , the length of front is about 600 m , which doesn't meet the need of enlarged production , In this paper, by study the reasonable advancing rate of working face and the inner dumping transportation distance and influence of the end slope to stripping ratio, after detailed and economical analy-sis. We det-erninate the reasonable length of front. |
