Stress Measurements of Deep Mining and Roadway Stability Control in Zhaogezhuang Coal Mine
The hollow included technique was used to measure in-situ stress of Zhaogezhuang coal mine in Kailuan mining area.According to the analysis of the measurement data,the characteristic of in-situ stress field is obtained.The result shows that the in-situ stress of Zhaogezhuang coal mine is based on leading of horizontal compressive stress,and the direction of the maximum principal stress NNW ~ NS.There is a large difference between the maximum horizontal principal stress and the minimum horizontal principal stress,the maximum principle stress shows a strong directivity.Under in-situ stress effect,roadway surrounding rock prone to emerge deformation and destruction which will affect safety production in coal mine.So road stability plays an important role in safety and efficiency production in coal mine.
