Embodiment 1

[0035] A copper mine invested by our country in Zambia has a designed annual output of 3 million tons. It adopts two-step subsequent paste filling with a filling capacity of 160m 3 / h. Such as figure 2 As shown, the three stopes of the mine 756-2MU-2 / 4 / 6 are now described for the application of the embodiment. The three stopes are 93-106m long, 8m wide, 13-14m high, and the stope volume is 10381m 3 ~11837m 3 , because the mine uses a low-cost, reusable flexible filling retaining wall with a height of 4-5m. In order to ensure the safety of the retaining wall, it needs to be filled twice to pass through the retaining wall. In order to improve the filling efficiency, continuous filling of the three stopes must be realized.

[0036] The continuous filling device used in this mine is briefly described as follows: the entrance of the four-way pipe 1 is connected to the filling rubber pipe 2 with an inner diameter of 175mm and a pressure resistance of 2.5MPa; the three outlets ar...

Abstract

The invention provides a multi-stop fast-switching continuous filling device and a use method thereof, which belong to the technical field of mine filling. The device includes a four-way pipe, a filling incoming pipe, a sedimentation tank module, a filling module, a stope connection module, a sedimentation tank connecting pipe, a valve and a flange. The entrance of the four-way pipe is connected to the filling incoming pipe through a flange. The three outlets of the pipe are respectively connected to the sedimentation tank module, filling module A, and filling module B through flanges, and valve switches are used to control the flow direction. The sedimentation tank module is connected to the sedimentation tank connecting pipe through flanges, and the filling module is connected to the stope connection module Through flange connection, the stope connection module is connected with the filling stope. The device has simple processing, low manufacturing cost, simple operation, and high practicability. It not only improves the single filling efficiency, but also eliminates the pipe moistening and washing processes when switching filling in multiple stopes, and has high practical value.

Description

technical field [0001] The invention relates to the technical field of mine filling, in particular to a multi-stop fast-switching continuous filling device and a use method thereof. Background technique [0002] With the exhaustion of shallow resources and the increasingly stringent national environmental protection requirements, filling mining has become an inevitable choice for many mines. For every mine, reducing filling cost and improving filling efficiency are the eternal pursuit goals. In particular, the improvement of filling efficiency directly affects mining efficiency and is of great significance to the improvement of mine production efficiency and economic benefits. [0003] One of the important ways to improve mine filling efficiency is continuous filling. Due to the different occurrence conditions of ore bodies in each mine, the filling methods are also different. When the mining is finished and the filling is started, it is necessary to build a filling retai...
