An internal moisture monitoring system and its layout method in an open-pit mine dump

Abstract

The invention discloses an internal moisture monitoring system of an open-pit mine dump and an arrangement method thereof. In the system, a moisture monitor is pre-buried in the dump and is connected to one end of a transmission cable; the transmission cable includes a signal wire and the power supply line; the power supply kit is placed on the surface of the dump, connected with the power line, and supplies power to the moisture monitor through the power line, and the power supply kit supplies power to the wireless transmitter at the same time; the wireless transmitter is placed on the surface of the dump, and the The signal line is connected with the moisture monitor; the signal receiver receives the signal transmitted by the wireless transmitter, and transmits the signal to the analysis center; the analysis center includes a computer and a memory for processing the signal. In the arrangement method, the slope sections of the dumping work are advanced or advanced in sequence, so that the transmission cables are arranged in an S-shape on the section of the dumping site. The invention solves the problem of the arrangement of monitoring sensors in the deep part of soil dumping, has stable signal transmission, low failure rate and little interference between soil dumping equipment and transmission cables.

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...
