CO2致裂器药卷最小起爆长度试验
Experimental Study on the Minimum Detonation Length of Carbon Dioxide Fracturing Device
摘要
Abstract
The minimum detonation length of cartridge for CO2 fracturing device is tested,and the blasting experiment was carried out stepwise by using the control variable method,and the blasting effect is analyzed theoretically.The optimal length of the cartridge in engineering application was discussed.The method of the obtained safety detonation volume and the method of increasing the explosive power of different types of fractures have a guiding role in coal seam gas drainage and rock fracturing.关键词
