| Abstract: | Taking No. 3206E coal mining face as an example, the paper analyzed the feasibility of gateway pre-heading technology in fault base on the key strata theory. With a distinct element software UDEC3.0, the paper has a optimized analysis of digital simulation on the support parameters. In consideration of the mining activity influence to the pre-heading of face gateway, the paper has set the rational support parameters of the face gateway pre-heading. The site practices showed that the support results were excellent. |
