| 摘要 |
The present invention includes a hydro-shearing apparatus, a hydro-shearing system, and a method of mining waste coal. The hydro-shearing apparatus includes a fluid supply line adapted to permit the transporting of fluid, a nozzle adapted to emit the fluid, a pump adapted to recover at least the fluid, and a fluid discharge line adapted to permit the transporting of at least the fluid. The method may include positioning the hydro-shearing apparatus at least fifty feet away from a high wall of waste coal, manipulating the hydro-shearing apparatus to a vertical position within twenty feet of the top of the high wall of waste coal, operating the hydro-shearing apparatus such that a fluid stream contacts waste coal material, recovering the coal product with the pump of the hydro-shearing apparatus, and transporting the coal product away from the hydro-shearing apparatus.
