摘要

Gateway supporting in long-wall mining has been a problem that restri cts the mine production and safety, the paper sets up an interaction model betwe en support and surrounding rock (rock mass structure) and probes the elementary theory about ground pressure behaviors of gateway. Based on the analysis of supp orting theories, some new viewpoints about gateways supporting and ground pressu re controlling are put forward.
