摘要
一个探采结合的小矿山,需要进行技术改造,扩大再生产。但是在坑口运输及开采方法方面,遇到了技术上的困难。在少花钱、少添设备、保证安全、多产矿石的条件下,选择一个合理的技术改造方案。本文正是这一方案的选择与论证。
A small mine controning exploiting and exploring needs to improve its techniques and enlerge its production. Tec??niquesdefficuties are controntable with exploitation method and adit entrance transportaion. A reasonavle schen?e of technique improvment isexpected to be laid under the conditions of less expeness, less purchase of equipment, more sefety and higher production of ore. A schemeon this subject is pro?osed and peovod in this paper.
