Abstract: According to the geological condition with the complicated and unknown features ,during the design on the gateway supporthe geogical ynanics enwronment in the underground mine would inconveniently and accurately understand and study was conducted on the gateway suppor ransparency system of the mime gateway in the mine. A hyrauilic fracturing method was applied to the dataclcion in site of undergrcund mine and to gethebas c srss of ining bock an surouding rock strength dala.According to the geoloical survey resuts from peephole and geological exploration seismic and other informations of the mining bock.based on the analogical right riangular prism data stucture,a geological model of the seam and roof stratain the mining block was esablised.Based on the ransparency geologcal bodywisual expressions of the mine gateway suppor plan were realized.Meanwhlie a geostressinerpolaion agorithm was applied to the dynanic calculation and seach on the geostress at any location within the miming block and the surounding rock stength data itin10 m scopeof the rof A suvdy on a mine wasimplemented and verfed could be qxuickly obtain the geostress data and could provide reliable parameters to the nitial design of the gateway suppor of the mining blck.
