Summary: | The invention discloses a well-ground combined long horizontal section dense fracturing gas rapid extraction method with a well replacing a roadway. The method comprises the steps that the deployment position of a horizontal well is determined; construction parameter design of the horizontal well is completed according to the earlier-stage exploration data, and construction parameters comprise the length of a horizontal section, the position of a horizontal well end hole, the length of a stable inclination section and a stable inclination angle; drilling and completion construction of the horizontal well is completed; an underground long drill hole is constructed in the main roadway open-off cut position in the upward inclination direction of the horizontal section, and butt joint of the underground long drill hole and the horizontal section is completed; fracturing construction of the horizontal section is completed section by section; after flow-back is completed, drilling and washing are conducted on the h |
