In-situ testing technology on deformation and destroy of coal seam floor during the mining
The deformation and destroy characteristics after coal mining are the key parameters for the coal mine safety production all the way.Specially for the working face being threaten by flood damage from the coal seam floor, the depth range of floor rock destroy after coal mining must be gained.Through the laneway conditions of mine, the ideal results can be measured in-situ by the geophysics methods.For example, using the seismic wave method or resistivity method in single drilling hole of floor rock strata, and using the electrical resistivity imaging method between two drilling holes of floor rock strata, the relevant characteristics of deformation and destroy in floor rock strata in the mining conditions can be judged dynamically according to the dynamic variation of physical property parameters.The testing results of physical property parameters have the different merits, such as imaging intuition, with good comparison, and with four-dimensional feature, and so on.It has good application effect.
