چکیده
Based on Spatial structure of the roadway, threedimensional geometric modeling of the roadway has been studied.It is separately gived that a detailed analysis of roadway centerline modeling, roadway cross-section modeling, roadway intersection modeling and an efficient data structure. Using VC++ and openGL, a specific test was carried out.This paper introduces a relevant algorithm in which the centerline dot is approximated by traverse dot and the cross-section located in tunnel’s node. Establish a three-dimensional model tunnel and achive a virtual display of roadway.

Extension of Excavation Damaged Zone Due to Longwall Working Effect
In advance longwall mining, the safety of mine network, production rate, and consequently, economic conditions of a mine are dependent on the stability conditions of gate roadways. The gate roadway stability is a function of two important factors: 1) characteristics of the excavation damaged zone (EDZ) above the gate roadway and 2) loading effect due to the caving zone (CZ) above the longwall w...
متن کاملComparing the “Modified Split and Fender” and “Shortwall” Methods for the Pillar Recovery in Room and Pillar Coal Mining Using A 3D Finite Difference Modeling in Tabas Central Coal Mine, Iran
Selecting a suitable pillar recovery method is one of the most important issues in the room and pillar mining. The main purpose of this study is to compare two methods for pillar recovery in Tabas central coal mine (TCM). Among the existing methods, the two methods, “Modified split and fender” and “Shortwall” are chosen for the numerical modeling. The three dimensional finite difference method ...
