Roadway Stability Analysis And Round Pressure Control Research Under Complicated Geological Conditions

In order to satisfy the enginnering need that making the chenchao iron refinery mining and engineering to develop deeply, it’s very important to study the factors which affecting the stability of surrounding rock of roadway. Through the survey of geological engineering, in the process which from the shallow to the deep development,we can find that the factors affecting the stability of surrounding rock of roadway are developing from one single factor to more factors.In this Paper, we studied the influence of roadway surrounding rock stability which causing by the structural face at first. Doing the analysis to a variety of structural planes by numerical simulation. Finding out the most harmful situation to the roadway and making suggestions to the design of roadway accordingly. Also doing the solid-liquid coupling analysis through the numerical simulation software. Analyzing the influence on the stability of the roadway which caused by the coupling effect of seePage field and stress field. Puting foward the improvement opionions to the roadway drainage. Designing the protection scheme of anchor to the surrounding rock of roadway under the complex condition. Analyzing the results of numerical simulation by using muti-objective fuzzy decision and choose the best scheme. Then optimizing the existing scheme design.The above research results have been applied to the mine production practice,and the results show that the optimized design scheme controling the refocing of Cheng Chao in a certain extent.It can make a safety production environment to the mine and can provide the reference for the other mines.
