首山一矿己二采区优化设计

Optimized Design on Ji-2 Mining Block in Shoushan No.1 Mine

在煤与瓦斯突出矿井,利用水平大巷生产系统施工,优化采区布置,把双翼采区分为两个单翼采区,从而保证每个单翼采区同时准备、同时生产,缓解了矿井采掘接替紧张的局面。该采区优化设计方法具有保证生产能力,提前开工早日见效、巷道工程量小、投资少、系统独立、安全可靠性高等特点。

In the coal and gas outburst mine, the production system of the mine level roadway could be applied to optimize the mining block layout. The two wing mining blocks could be divided into two single wing mining blocks to secure the simultaneous preparation and simultaneous production of each single wing mining block and to release the connection tension between the mining and excavation in the mine. The optimized designed method of the mining block could secure the production capacity and make a early production. The optimized designed method could have the features of the low roadway construction, low investments, a system independent and high safety reliability.
