摘要
基于龙山矿井薄煤层赋存情况,提出了4种辅助运输方案,从初期设备静态投资的角度进行了经济分析,该矿井初期4种辅运方式总投资相差不大,但考虑设备维护及使用寿命,认为井筒采用绞车井下采用无极绳(卡轨车)更有利。
Based on condition of thin coal seam occurrence in Longshan mine,put forward four kinds of auxiliary transportation scheme,analysed from the angle of the initial static equipment investment economic,the mine early four auxiliary means total investment were similar,but consider the equipment maintenance and service life,the wellbore downhole with endless rope winch(card rail car)is better.
