Abstract：The support of soft rock roadway is always a key technical issue influencing the safe production in coal mines, especially in the soft rock roadway with high ground pressure in the deep mine, ground behaviors appeared clearly and the roadway support became more difficult. The combined support technology using “anchor mesh, cable and bolting shotcrete” was adopted in Qidong Mine of Wanbei Coal-Electricity Group Co. , Ltd. , rational supporting technique and parameters were determined, the displacement of the roadway surface was monitored, the deformation and damage of the soft rock roadway with high ground pressure in the deep mine was under effective control, and better support effect was achieved.
