A filling stope closure device and system with monitoring function

Abstract

The invention provides a filling stope closure device and system with a monitoring function, and relates to the technical field of filling stope closure devices. The filling stope closure device with a monitoring function provided by the invention includes a framework and a fixing device connected to both ends of the framework. The frame, the skeleton includes a plurality of arc beams, and at least one of a pressure monitor, a strain monitoring component and a displacement monitoring component; the pressure monitor is sandwiched between the fixed frame and at least one end of at least one arc beam between; the strain monitoring component is installed on the inner arc side of at least one arc beam; the displacement monitoring component is located on the inner arc side of multiple arc beams. The above-mentioned filling stope closure device can effectively monitor the mechanical and deformation characteristics of the closure skeleton as the main force-bearing unit, and provide data for timely and accurate grasp of the mechanical state of the closure device during the filling process and to judge the overall reliability and stability of the closure device support, and after the monitoring is completed, each monitoring structure can be recycled, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of filling stope closure devices, in particular to a filling stope closure device and system with a monitoring function. Background technique [0002] The filling mining method used in underground mines needs to seal the underground space before filling. The commonly used sealing methods are roughly divided into two types: rigid sealing and flexible sealing. The former is represented by a rigid retaining wall of concrete structure. There is a water outlet hole on the wall to drain excess water in the filling stope. The sealing structure does not allow deformation and displacement, which has a large bearing capacity and high cost; the latter adopts a combination of skeleton structure and dewatering structure. Most of the skeletons are steel structures, and a few are wood supports, with small bearing capacity and low cost. The filling closure device (or closure door) is used as a stressed member supporting th...

Problems solved by technology

[0004] The above scheme detects the wall pressure for the rigid retaining wall structure, and can realize the pressure detection of the measuring points after the inner slurry covers each measuring point. However, this detection scheme has the following technical defects and deficiencies: (1) The sensor is placed Inside the retaining wall, it is not recyclable, and the one-time landfill cost is high, which inevitably causes waste

With the hydration and solidification of the filling slurry in the filling stope, the static pressure tends to be stable or returns to zero, and the pressure detection will lose its engineering significance. However, the rigid retaining wall is not easy to disassemble and is generally not disassembled. recycling, waste

(2) The layout of measuring points is limited, and the number is large, and the cost is high

For conventional filling retaining walls, the section range is 15m 2 to 20m 2 Left and right, if the whole section is sampled, it is necessary to use a dot matrix layout device for the sensors, which requires a large number. If necessary simplification is adopted, the vertical and horizontal cross layout is selected. Although the number of sensors can be reduced, the range of measuring points becomes narrower and more reliable. decreased sex
