This paper introduces dynamic information method under small coal pillar and large over-the-roadway roadway groups influnenced by full extraction and structure,building large model simulates diffierent reinforcing scheme and supporting parameter,the best scheme is obtained,through analyzing rock pressure,this method is rational and reliable.

By the numerical simulation, the surrounding rock deformation and failure regularity of the cross mining roadway have been researched, the advanced and hysteretic influence to the roadway groups under the cross mining condition has been determined.

This paper takes the stability of roadway group under influence of strip mining as the main subject of investigation.

In order to understand the abutment pressure distribution regularity of work face and its effect on the roadway group under mining,the lateral abutment pressure of Xinzhuang Mine working face was observed by the ZYJ rigid drilling stress sensor and "ten words method".
