Abstract: Aiming at the problem of roadway support and rock stability of 31203 mining face in ShiGeTai coal mining, Through field measurements and numerical simulation methods,Study on the damage characteristics of the leading section under the influence of primary mining along the main transportation laneway，The results show：the main transportation laneway’s roof support is oversupply, 30 meters ahead of the working surface is affected by it, The features of non-uniform destruction of the submarine appear within 15 meters in front of the working face, Upper and middle parts of the coal wall need to be reinforced and supported,and the weakening scheme of roof support and reinforcement scheme of coal wall support was proposed, the safe production of coal mines was ensured,andthe reference for similar roadway surrounding rock control was provided.
