近年来,由于地下无轨采矿技术的不断发展,一些新的高效率采矿方法相继出现。无底柱分段充填采矿法就是在上向分层充填采矿法的基础上,采用深孔钻机凿岩和端部放矿的一种变型方案。它具有作业安全、劳动生产率高、采矿强度大和成本较 In recent years, due to the continuous development of underground trackless mining technology, a number of new and efficient mining methods have emerged. Bottomless subsection fill mining method is based on the stratified charge mining method, based on the use of deep hole drilling rig rock drilling and end of a variant. It has operational safety, high labor productivity, high mining intensity and cost
