Analysis of Antireflection and Outburst Prevention Mechanism on Hydrofracture Technology in Soft Coal Seam

Abstract:

Base on the hydraulic fracturing field test in soft coal seam, the rule which the cutting quantity is added and the drilling gas desorption index K1 is decreased, is analyzed from the perspective of physical-mechanical properties and adsorption-desorption law is changed, etc. And gas adsorption and desorption law was analyzed using the theory of two-phase flow, to determine the effect after fracturing coal extraction is improved and the main reason for reducing the outburst.
