Experimental study on mechanical properties of coal rocks in re-fracturing
Taking high rank coal in Qinshui Basin as the research object, the mechanical parameters of the coal rocks after primary fracturing with quartz sand filling the fracture are measured, and the variation law of the mechanical properties of the coal rocks after sand filling is analyzed to provide relia...
