Experimental Study on Pressure Relief Mechanism of Variable-Diameter Borehole and Energy Evolution Characteristics of the Surrounding Rock
Conventional borehole pressure relief can meet the requirements for preventing rock bursts, but it can also easily destroy the roadway, resulting in system support failure. Taking coal-like samples with boreholes as the research object, the pressure relief effects of the same-diameter boreholes and...
