The invention provides a safe and rapid
evaluation treatment method for overlying strata
water diversion under working face mining, in the treatment method, before working face
stoping, a waterproof curtain is constructed along the boundary of a surface
subsidence range, the waterproof curtain extends into a
bottom water-resisting layer from the surface, so that the waterproof curtain is constructed along the
vertical projection direction; and the bottom
aquifer in the surface
subsidence range is completely sealed by the waterproof curtain, so that water inside and outside the waterproof curtain does not interfere with each other, and the
water volume influencing the
stoping of the working face is reduced. A plurality of
water level and crack monitoring assemblies are arranged at the same time, in the
stoping process of the working face 1, the
water level condition in a waterproof curtain and the crack condition generated by sinking of a bottom waterproof layer are monitored in real time through the
water level and crack monitoring assemblies, and corresponding treatment measures are taken according to the corresponding conditions; the waterproof curtain, the grouting operation and the
water pumping operation cooperate with one another, the effect that no water is stored in the waterproof curtain is achieved, meanwhile, the construction cost can be greatly reduced, the construction efficiency is improved, and the
ecological environment is protected.
