超长综放工作面经济效益分析

综采放顶煤技术已成为厚煤层开采的高产高效采煤技术。布置超长综放工作面 ,不仅能提高单产 ,减少巷道掘进率和维护量 ,减少回采成本及搬家倒面次数 ,而且能减少设备占用 ,提高资源采出率和劳动生产率 ,简化生产系统 ,实现合理集中生产。通过类比的方法 ,分析了超长综放面在经济效益上优于普通综放面 ,提出了提高矿井综合效益的方法。

Analysis of Economic Effectiveness in Superlong Fully-Mechanized Mining Workface

Fully mechanized caving mining has became mining technology of high output and efficiency in thick coal seam mining.With superlong fully mechanized workface,not only improving production,reducing cost of overhead mining and frequency of carry,but also reducing equipment occupied improving resources productivity and work productivity.Simplifing production system,realizing central production.Through this way is known:superlong fulling mechanized workface is better than common in economic benefit.So it is a way to improve comprehensive benefit.
