Technology Practice of Backfill Mining Under Highway

In recent years, the mining rate of coal resources enlarges in our country, and the coal resources under highway are becoming more increasingly. The problem that coal resources can be extracted becomes urgent under the condition that highway can run normally, which need be solved. The influence of coal mining under highway mainly includes vertical and level deformation. Combined with the example of coal mining under highway, through the analysis and contrast with related data about the Gonggeyingzi Coal Mine, mining with backfill can achieve the goal of mining coal, the safety and the green mining.
