Adaptive filling system capable of regulating pressure at multiple stages and pressure regulating method thereof

Abstract

The invention discloses an adaptive filling system capable of regulating pressure at multiple stages and a pressure regulating method thereof. The system comprises a control module, a pressure reliefmodule and an energy dissipation and decompression module, wherein the pressure relief module and the energy dissipation and decompression module sequentially communicate on the part, between drilledholes, of a filling pipeline. The pressure relief module comprises a pressure relief unit and a first bypass pipeline communicating in parallel on the filling pipeline, the energy dissipation and decompression module realizes different levels of decompression measures through parallel connection to multi-stage energy dissipation and decompression units and a second bypass pipeline in the filling pipeline; valves are arranged on the pressure relief unit, the first bypass pipeline, the multi-stage energy dissipation and decompression units and the second bypass pipeline, the control module is used for acquiring stope position information in real time, through the position information, height difference between a filling preparation station and a stope is acquired to obtain a residual pressure head P, and according to the residual pressure head P, on-off of the valves of the bypass pipeline, the pressure relief unit as well as the energy dissipation and decompression units are controlled.The system can carry out multi-stage automatic pressure regulating according to the residual pressure head of a mine, and reduce the failure phenomena such as pipe bursting, excessive jet velocity atan outlet and pipe plugging.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to an adaptive filling system capable of multi-stage pressure regulation and a pressure regulation method thereof. Background technique [0002] Under the existing industrial technical conditions, the filling and filling mining method can not only ensure the safety of production to the greatest extent, but also have two remarkable characteristics of protecting the environment and improving the recovery rate of ore. More and more widely used and developed. In the filling mining method, pipelines are used to transport the filling slurry to backfill the stope. At present, the filling pipeline transportation system is usually constructed once. After the construction is completed, the pipeline transportation system passively transports the filling slurry, and the pipeline system cannot be self-adapted according to the size of the remaining water head. Adjustment. [0003] For long-dista...
