The Strip Mining Of Technology Research On Under-buildings

In order to allow those ground buildings have a small influence, it needs Optimal Design to Linnancang coalmine East 2th district with strip mining at the same time improve its recovery ratio ,and then choose the most reasonable mining programmers and parameters.By using theoretical analyzing, numerical simulation and spot surveying in this paper, and 3 wide strip mining schemes are proposed with different mining width and the same coal pillar, and it tested the coal pillar's stability to each scheme; By using probability integral method and Flac3D program, predicted the surface subsidence and deformation value; In the end, by compared them with the value gotten from spot survey, we get the most suitable wide strip mining scheme, and get the most reasonable mining width value.As a special mining method, strip mining method can resolve the problem of hosting mine under the buildings, can improve recovery ratio at the maximum. As the increasing of this mine's production, it can bring to mine district with remarkable economic and social performance.
