The article reveals the application experience of directional hydraulic fracturing to reduce rock heaving intensity in the development opening of the following longwall face. The authors developed a scheme of roof weakening at longwall exit from the installation chamber. It also helps prevent rock heaving in conveyer roadway 2593. The mechanism of rock heaving was studied. The authors determined the scheme of mine pressure distribution and rock heaving in the conveyer roadway at coal extraction in the longwall face. The authors measured the rock heaving values along the working considering the held activities. The authors made conclusions and gave respective recommendations.
