Study of Deformation and Breakage Characters in Coal Seam Floor under the Condition of Mining

Abstract:

Article Preview

The water bursting disaster from the floor of mine is a complicated program involving several of subjects such as geology, coal mining, rock hydraulics and rock crack mechanics. In the paper, the two dimensional non-linear solid-fluid coupling model is used to study the difference of the water-holding capacity of the different floor combination under the condition of mining. The mini damage rock layer combination is obtained by analyzing the failure extent of floor under the mining pressure and water pressure. The water resisting capacity of the combination of b is the worst. The water resisting capacity of the combination of c is the best.
