Study on Improving Coal Penetrability with Water Pressure Blasting

摘要：

The characters of water pressure blasting, traditional crack-making with infuse andtraditional crack-making with blasting is analyzed and the mechanism of water pressure blasting tocause split in coal seam is also analyzed. The field test of water pressure blasting was carried out inNiuerzhuang coal mine of Fengfeng mining bureau. The attenuation rule of natural flux and the changeof methane from the hole pre-and-aft blasting were observed. Finally the test results have proved thatwater pressure blasting is the better method to improve the penetrability of coal seam effectively and thepump flux of the hole pre-and-aft blasting increased 3 times.
