Study on Key Controlling Factors of Fracture Propagation by Shaped Charge Blasting in Coal Seams
Energy Science &Engineering, EarlyView.Gas drainage is the fundamental approach to controlling gas disasters in coal mines. For single low‐permeability coal seams, it should be supplemented by coal seam permeability enhancement technologies to improve gas drainage efficiency. This paper conducted a numerical simulation study on the key controlling factors affecting the fracturing effect of ...

Energy Science &Engineering, EarlyView.ABSTRACT The powered roof supports in the longwall complex are placed and interconnected next to one another, typically about 125–250 units in a longwall face. It is an essential component in the longwall complex, which also includes a shearer (or plow) and an armored face conveyor.

Energy Science &Engineering, EarlyView.This work reveals the “C‐Y,” double “Y,” “π,” and “Y” fracture modes of thick, hard strata and their progressive breaking process (O‐F‐R/S mode), providing a theoretical basis for controlling strong ground pressure in deep mining. ABSTRACT In response to the dynamic hazards caused by the fracture of thick‐hard strata in deep mining, this study ...
