结合阳煤集团新元公司特殊的地质条件，设计了底板预抽巷实施水力压裂的试验方案，通过对试验结果的分析讨论压裂参数选取的合理性，确定了压裂压力和压裂半径，并获得的了压裂煤体中瓦斯压力分布规律。本文的研究结果可为相似地质条件下的煤层水力压裂参数选取提供依据。%Based on the geology conditions of Xinyuan Coal Mine , the test plan of hydraulic fracturing form floor drainage roadway was designed .Through the analysis of the test results , the rational fracturing parameters , such as fracturing pres-sure and fracturing radius are determined , and gas pressure distribution rule in fractured coal was achieved .The research can provide reference basis for determining hydraulic fracturing parameters in similar geological conditions .
