Rapid Driving Technology and Surrounding Rock Control Technology of Coal Roadway in Coal Mines
In the upgrading of mining technology,rapid driving technology has been widely used,but when combined with the control of roadway surrounding rock and rapid driving technology,it is easy to be affected by mining and complex underground environment,resulting in support problems.Therefore,the geological environment and rapid driving technology were analyzed to provide data support for support control by taking the driving of transport roadway of 1440 working face in a coal mine as an example.Then,research was carried out from the perspective of numerical simulation,which can clarify the value range of support parameters.Three support schemes were designed,and the design of surrounding rock support schemes was completed based on the technology of rapid driving unit after verification.Finally,industrial tests were carried out to improve the safety of roadway support.
