Problems solved by technology

Because the traditional pipeline flows a homogeneous body, the pressure and sewage discharge are easier to handle, while the paste filling transports a heterogeneous body, which is easy to block the pipe
Once the tube is short, the entire filling system will be greatly damaged

Abstract

The invention provides a paste filling pipeline system for a coal mine. The system comprises filling pump reversing equipment, a paste filling, pipe plugging and discharging gate with a pressure detection function, a paste filling pipeline expansion and contraction device, a paste filling trunk pipe blow down valve and a paste filling pipeline cleaning flow regulating and controlling device whichare connected with one another through a straight pipe, a pipe clamp, a tee joint and the like. By adopting the paste filling pipeline system, effective pipeline conveying and monitoring of large-particle paste filling bodies are fully realized, and the pipe plugging accident is avoided.

Description

technical field [0001] The invention relates to a coal mine paste filling equipment. Background technique [0002] With the reduction of coal resources in our country, more and more attention has been paid to the mining of coal resources under some buildings, water bodies and railways (highways). Since mining under some special conditions will have a huge impact on surface buildings, structures and dams, the implementation of paste filling mining technology is of great significance to the safe production and sustainable development of coal mines. Because the traditional pipes flow homogeneous bodies, the pressure and sewage discharge are relatively easy to handle, while the paste filling conveys heterogeneous bodies, which are easy to block the pipes. Once the tube is short, the entire filling system will be greatly damaged. Therefore, the key to coal mine paste filling mining technology lies in the reliability of the filling pipeline system, and it is urgent to develop a ...
