Asymmetric floor heave mechanism and groove cutting pressure relief control technology in mining roadways
In mining roadways located between solid coal and small coal pillars, the problem of asymmetric floor heave is severe due to the influence of factors such as asymmetric support pressure, plastic deformation of small coal pillars, and weak floor strata. Traditional support technologies are difficult...
