摘要
印尼Ombilin煤矿1号井是印尼国家煤炭公司PTBA旗下的一个井工煤矿。由于井工开采效益差,综采设备零部件供货困难等原因于2005年暂停煤矿生产。随着近几年印尼煤价的持续走高,该矿决定重新进行井工煤炭生产,在最大限度利用原有巷道及硐室的基础上对采区进行优化设计,保证最短的时间内完成技术改造和煤矿的恢复再生产。本文通过研究该矿的现有巷道布置,对工作面布置提出了2个方案,通过方案比选,最终确定工作面布置形式和接续顺序,为该矿的恢复再生产提供了科学合理的设计方案。
Ombilin 1# coal mine belongs to Indonesian stare owned coal compaey PT]3A . Due to unsatisfactory economic efficiency arid shortage of components supply for the fully--mechanized mining equipments, the mine shut down its production in 2005. With the uprising coa] price, the raina owner decided to re-open the mine and achieve re-production at the shortest time on the basis of utilizing most of the old galleries and chambers as weli as optimizing the mining section. The paper analyzed existing conditions arid proposed 2 options for workface arrangement. After comparison, the workface arrangement and succession is determined, which provide a scientific and reasonable design for mine. re-production.
