Research on Development of Visual Calculation Analysis System for Optimization Design of Width Left for Mining of Strip Mining

Xie Feihong (School of Civil Engineering, Lanzhou Jiaotong University)  
The subsidence deformation mechanism of strip mining is briefly presented. On the basis of this and according to the correlative regulations, a set of tool to calculate estimated width left for guiding mining of "Sanxia" mining is developed. It is used in the engineering practice and achieves good effects.
