摘要
从水力采煤万吨掘进率高 ,煤炭运输、提升电耗大等特点来看 ,水采工作面煤层厚度在 2 .0 m以上 ,特别是 3.5m以上的厚煤层 ,其开采经济效益显著。同旱采矿井相比 ,如何抓好厚煤层水采工作面的开采强度 ,提高台枪年生产能力 ,是水采矿井提高单产的关键。
Hydraulic coal mining features higher drivage ratio per 10,000 ton of coal mined and high power consumption of coal transport and hoisting operations.Nevertheless in mining seams with a thickness of greater than 2.0 m and in particular the ultrathick seams above 3.5 m in thickness,a remarkable economic result can be gained.Through comparison with conventional mine,it has been found that the key of enhancing face capacity lies in increase of face mining intensity and the annual capacity of each monitor.
