Stress displacement monitorable strip mine slope coal pressing recovery method

The invention discloses a strip mine slope pressed coal recovery method capable of monitoring stress displacement. A mining cave is mined in a soft rock stratum; a filling station is arranged at the uppermost flat plate of the slope top, and a filling pipeline is arranged downwards from the bottom of the filling station to the mining cave along the slope surface; after one mining chamber is mined, the reinforcement cage is sent into the mining chamber, and an inclination measuring device and a force measuring device are arranged on the reinforcement cage; feeding the reinforcement cage into a filling station after the mining chamber, injecting a liquid filling material into the mining chamber through a filling pipeline, and forming an in-situ filling pile after the liquid filling material is solidified; the soft rock stratum is replaced by the in-situ filling piles, the overall stability coefficient of the side slope is remarkably improved, the final side slope angle is increased under the condition that the
