Discussion on junction point construction technique under complicated geological conditions of deep wells
Abstract：With the increase of the depth and intensity of coal mining, the construction of roadway junction point has been facing more and more unfavorable engineering technic conditions. This paper analyzes and discusses the main factors of influencing the stability of junction points under complicated geological condition of deep wells, namely tectonic stress, soft rock, roadway space structure and the mechanism of wall rock deformation mechanics. For complicated geological condition of production, a targeted construction way and scientific supporting system are used, which improves the construction speed of junction point and attains good supporting results.
