Floor Destruction Characteristic Study of Confined Water Effected by Mining Conditions
Combined with Huaibei Mining Group 1028 Face of the Sun Tong mine site conditions,elasticity in the plane semi-infinite body established by the base plate of a mechanical model in the triangle strip load was used.The bottom plate of arbitrary point in the state of stress was analysised,and calculation formula of the horizontal stress,vertical stress and shear stress.was deduced.Based on elastic-plastic theory for solving the floor failure depth calculation of the floor limit conflict,the size of the water inrush combined with the Sun Tong mine 10 coal aquifer water inrush stress was analysised.The results of theoretical analysis of this article has some guidance,for the site management of the Sun Tong mine and has some reference for similar conditions.
