Study on stress distribution and support technology of surrounding rock in dynamic pressure driving roadway<br>Hu Qing Jun<br>(Shaanxi Chenghe Shanyang Coal Mine Co., Ltd. Shaanxi Weinan 715300)<br>Abstract: the distribution of surrounding rock pressure in dynamic pressure driving roadway is to transfer or release the high pressure around the roadway to other areas on the basis of roof cutting and pressure relief technology, so as to ensure that the surrounding rock of the roadway will not be deformed and damaged due to the pressure. In this way, the deep surrounding rock of the coal pillar of the roadway can be fractured and the supporting pressure can be eliminated. If the roadway is in the low ground stress area, the difficulty of roadway support can be reduced and the safety of mine construction can be improved.<br>[Key words] dynamic pressure driving; roadway surrounding rock; support technology<br>
