System for monitoring moisture in open-pit mine dump and arrangement method of system

Abstract

The invention discloses a system for monitoring the moisture in an open-pit mine dump and an arrangement method of the system. In the system, a moisture monitor is pre-buried into the dump and connected with one end of a transmission cable; the transmission cable comprises a signal line and a power supply line. A power supply suite is arranged on the surface layer of the dump and connected with the power supply line and supplies power to the moisture monitor through the power supply line, and the power supply suite supplies power to a wireless transmitter at the same time; the wireless transmitter is arranged on the surface layer of the dump and connected with the moisture monitor through the signal line; a signal receiver receives a signal transmitted by the wireless transmitter, and forwards the signal into an analysis center; the analysis center comprises a computer for processing the signal and a storage. In the arrangement method, through successive advance or normal advance of dumping work grade sections, the transmission cable is arranged in an S shape on the section of the dump. By means of the system, the problem about arrangement of a monitoring sensor in the deep dumpingpart is solved, the signal is stably transmitted, the fault rate is low, and the interference between a dumping device and the transmission cable is small.

Description

technical field [0001] The invention relates to an internal moisture monitoring system of an open-pit mine dump and an arrangement method thereof, belonging to the field of open-pit mining. Background technique [0002] The dump is a large artificially constructed rock-soil body in the production process of the open-pit mine. It is used to stack the overlying rock and soil stripped during the production process of the open-pit mine. , The permeability changes, and the water stagnation effect is obvious. With the external water supply, the internal water content and groundwater level will also change significantly. At the same time, the long-term pressure and impregnation of rock and soil will cause certain changes in the type, thickness and position of the water-resisting layer inside the pile, which will lead to changes in the height of the water head and water pressure inside the dump, and then affect the stability of the dump. When the water content inside the dump is hi...
