Research on the Manifestation Law of Mining Pressure and Optimization of Coal Mining Technology in Fully Mechanized Mining Face
In response to the frequent occurrence of bracket movement,tilting,difficult expansion and contraction,and equipment overturning in a certain mine,numerical simulation,on-site measurement,and similar simulation methods were used to optimize the coal mining process of a large angle working face in a certain mine.By analyzing the movement,damage,and stress laws of the surrounding rock and roof of the large angle working face in a certain mine,the mining pressure monitoring and mining pressure manifestation laws of the fully mechanized mining face in a certain mine were studied,and the coal mining process of the large angle fully mechanized mining face in a certain mine was optimized to ensure the safety of the working face and make the production of the large angle fully mechanized mining face in a certain mine safer and more efficient.
