摘要
Abstract
Through the analysis of hydraulic flushing and hydraulic fracturing technology, the advantages of two hydraulic measures were integrated, the principle of pressure relief and permeability improvement technology of the integration of hydraulic flushing and hydraulic fracturing was studied, the applicable conditions of technology were introduced, field industrial tests were carried out. Field industrial test results shows that: the technology of the integration of hydraulic flushing and hydraulic fracturing can ef-fectively improve gas extraction concentration and purity quantity of gas extraction, and then shorten the time of meeting the stan-dard of gas extraction in coal seam, it can also provide important technical support for safe and efficient production of coal mine.关键词
