影响采区边角块段煤层回收率的原因及对策

Causes of Low Recovery Rate of Margin,Angle,Block and Member of Coal Layers in Mining Fields and its Countermeasure

针对矿井后备资源紧张的局面及采区边界残留块段普遍存在的现状,提出加强对采区边界煤层进行回采的几种措施,杜绝采区边界残留块段的产生,从而提高矿井煤炭资源利用率,实现经济效益的最大化。

With the development of Chinese coal mining, coal resource is becoming deficient while abandoned coal layers of margin, angle, block and member are ubiquitous. Several methods to strengthen retaining of the margin coal beds are raised. The usable rate of the coal resource is increased. The maximum economic benefit is realized.
