This invention provides a physical
simulation experimental device and method for fine exploration of water-bearing sections in underground rock strata. The device includes a
water storage tank connected to a water pump. The water pump is connected to one end of multiple
water supply valves via a one-way valve. Each
water supply valve has a corresponding rock chamber at its other end. These rock chambers are vertically mounted on the sidewall of a simulated borehole
pipe.
Flange end caps are installed at both ends of the simulated borehole
pipe. A return water inlet sealing head is installed on the
flange end cap at the
tail end of the simulated borehole
pipe. The return water inlet sealing head is connected to the
water storage tank via a return water valve. An
energy storage and
voltage regulator is also installed between the
water storage tank and one end of the multiple
water supply valves. An armored
optical fiber cable for
acoustic wave sensing is coaxially installed inside the simulated borehole pipe. This invention can effectively simulate various geological and hydrological conditions in actual underground rock strata environments. By analyzing the variation patterns of acoustic signals, it improves the accuracy of exploration of water-bearing sections, providing reliable
technical support for
coal mine water
hazard prevention and safe production.
