Preliminary Tests of Coal Reservoir Permeability Enhancement by Controllable Shock Waves in Baode Coal Mine 8# Coal Seam
摘要
Abstract
This paper presented a series of preliminary tests to enhance the coal seams permeability of Baode Mine with CSW technology. One test hole, two observation holes in the near area and two observation holes in the far area were designed to analyze the effective permeability improvement area. The results show that the gas extraction from 1# and 2# holes near the test increases significantly and presents an obvious increasing trend, while the gas extraction from 3# and 4# holes in the far area increases significantly, but the increase values are not significantly. It is revealed that the crack field after controlled shock wave operation has abundant development in the near region and relatively few permeability improvement characteristics in the far region. It is preliminarily determined that the effective radius of shock-induced crack permeability improvement coal seam is greater than 15 m. Through data comparison and analysis, it is proved that there are optimal times of action of shockwave permeability improvement coal seam.关键词
