煤体注水压裂技术——一种提高煤炭回采率的有效方法

Technology Coal Body Note Water Pressure Splits-One Kind Improves Back Production Effective Method of Coal

煤体注水压裂技术是有别于传统煤体注水软化技术的新型技术,它改变了以往注水软化技术长孔、低压、稳流的特点,利用高压水所具有的切割、压裂特性,压裂破坏煤体,降低煤体硬度,提高煤炭可放性。

Technology mat coal body note water pressure splits is the new- type technology that dillerent from traditional coal body water flooding and soften technology. It has changed the past note water and softermod technology, characteristic of the long hole, low - voltage, the stationary flow, Utilize high - pressure cut had of water, press the characteristic of splitting, destroy coal body to split to press, reduce coal body hardness, the performance that may blast down the roof to improve coals.
