The invention discloses a method for multi-section blocking of
overburden failure section and synchronous leakage measuring. The operation step includes boring upcoming holes with 30-50m depth in top-board rock stratum in a
coal rock lane, installing a detection
system and sending the detection
system to the initial position of the bored holes, enclosing the bored holes with a plugging
system, sending a
water source with specific pressure to a water inlet
pipe through a
water flooding operating bench, controlling the
gas pressure in a plugging
capsule to be slightly higher than the
gas pressure and the
water pressure in a water returning
pipe in a blocking chamber, correcting the
water pressure in the water returning
pipe, measuring the running water vector parameters, starting an electronic recorder and providing corresponding
water source pressure after the
water pressure in the water returning pipe is adjusted to a reasonable water pressure scope, recording
water flow data and other related data after stabilizing,
processing and analyzing collected data to form corresponding running water vector graph of the measuring section, and repeating the above steps to sequentially measure the bored holes. Multi-section and synchronous measuring top-board water guiding
cracking section at any angle can be realized.
