某矿废石提升系统方案设计与实践
|
摘要
某矿山是生产矿山,设计生产规模750万t/a、废石量48万t/a,井筒的排岩能力48万t/a。实际生产过程中每年有90万t的废石量,排岩能力严重不足,约40万t左右的废石需倒入溜破系统,混入矿石由主井提出地表。混岩导致金属量及经济效益损失巨大,急需增设废石提升系统,以解决矿山排岩问题。根据多方案比选,设计合理的废石提升系统,并在实际中加以运用,很好的解决了瓶颈问题,对同类型地下矿山排岩具有借鉴意义。
A certain iron mine is a production mine. The design and production scale is 7 million 500 thousand t/a, the waste rock volume is 480 thousand t/a, and the rock discharge capacity of the shaft is 480 thousand t/a. In the actual production process, there are 900 thousand T of waste stone each year, and the capacity of rock drainage is seriously insufficient. About 400 thousand T of the rock should be poured into the sliding system, and the ore is put on the ground by the main shaft. Because of the huge loss of metal and economic benefits, it is urgent to add waste rock lifting system to solve the problem of rock disposal. According to the selection of multi scheme ratio, a reasonable design of the waste rock lifting system is designed and applied in practice, which solves the bottleneck problem well and has a reference to the same type of underground mine drainage.
