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。
Fully mechanized top coal caving technology has become a high-yield and high-efficiency coal mining technology for thick seam mining. Arrangement of ultra-long fully mechanized face, not only can improve yields, reduce the tunneling rate and maintenance volume, reduce the cost of mining and move the number of faces, and can reduce equipment occupancy, increase resource recovery rate and labor productivity, simplify the production system to achieve Reasonable concentration of production. Through analogy method, it is analyzed that the ultra-long fully mechanized coal caving face is superior to ordinary caving face in economic benefit, and the method to improve comprehensive benefit of mine is put forward.
