A multi-field coupling research device for paste filling and its application method

Abstract

The invention provides a paste filling multi-field coupling researching device and an application method thereof, belonging to the field of refined researches of a paste filling mining technology. According to the device, a cylindrical material containing barrel is located at the central position of a maintenance box; the cylindrical material containing barrel is fully filled with paste filling materials; a sealing cover of the material containing barrel covers the top of the cylindrical material containing barrel; the outer part of the cylindrical material containing barrel is sleeved with a fixed cylindrical barrel; a heat insulation material of the material containing barrel is tightly filled between the cylindrical material containing barrel and the fixed cylindrical barrel; a sensor is buried in the paste filling materials; a dial indicator is fixedly arranged above the material containing barrel; the dial indicator is fixedly arranged at the outer part of the maintenance box by a bracket; a measuring rod of the dial indicator is fixed by a guide barrel, heat insulation cotton is fully distributed between the measuring rod of the dial indicator and the fixed cylindrical barrel; the connection part of the maintenance box and the dial indicator is sealed by a sealing material; a data collector is connected with the sensor and is connected with a computer; a whole testing device is arranged in the maintenance box. The device is simple to manufacture, small in volume and high in intelligence, and is suitable for paste filling material multi-field tests for adding gel materials in various mine enterprises of colored and black coal mines and the like.

Description

technical field [0001] The invention belongs to the fine research field of paste filling technology, mainly measures the performance evolution of paste under multi-field conditions, and is of great significance for safe and economic paste structure design. Background technique [0002] Tailings ponds and goafs are considered to be two major sources of danger in non-coal mines. The dam failure of tailings ponds not only threatens the safety of people's lives and property, but also causes large-scale environmental pollution and serious ecological damage. Full tailing paste filling is an important measure to effectively coordinate safety and environmental issues between tailings ponds and goafs. Since the development of paste filling mining technology, its application has been relatively mature. In order to further reduce the filling cost and speed up the mining and filling cycle, the technology is being forced to develop in the direction of refined research. [0003] Paste f...
