Surrounding Rock Control Technology of Mine Roof Flooding Roadway
With the continuous advancement of underground mining in coal mines,it will be affected by the harsh underground environment,mining disturbance and geological characteristics,and there are many challenges in surrounding rock control.Taking the excavation of roof flooding roadway as an example,it is necessary to strengthen the support work in view of the impact of water flooding.Therefore,based on the basic overview of the case coal mine and the understanding of the problem of tunnel excavation,the theoretical strategy of roadway surrounding rock control was proposed,and then combined with the actual excavation situation,the surrounding rock control schemes such as temporary support,permanent support,drainage and construction management were formulated from various aspects.After the practical application of the surrounding rock control scheme,the overall support effect was good,which can reduce the influence of roadway water and improve the safety of underground mining.
