Siphon sluicing method

Abstract

The invention relates to a siphon sluicing method, which is mainly applied in the mining process of tailing filling. Before a stope is filled, a drain-pipe is arranged in a pedestrian sluicing well, one end of the pipe is placed in the stope with a water mark and a weight, while the other end is placed in an ore discharging roadway and connected with a water supply pipe through a three-way pipe. The water supply pipe is provided with a first valve. The drain-pipe is provided with a second valve and a third valve which are closed at the time. After sand and water are stopped in filling the stope, and after depositing and clarifying 1 hour the water to be filled, the first valve is closed, and the third valve is opened; when water in the water supply pipe enters the stope along the drain-pipe, the third valve is closed, opening the second valve is opened, water in the stope is discharged to the ore discharging roadway along the drain-pipe; after discharging the filling water in the stope completely, the second valve is closed to wait for the next filling, and he previous step is circulated. The siphon sluicing method ensures that the sluicing time is short and the work efficiency is high during tailing filling in the stope.

Description

technical field [0001] The invention relates to a filling mining process, in particular to a siphon drainage method for tailings filling mining. Background technique [0002] The mechanized tailings filling mining method in the upper wall access panel of the footwall connection road is completed by the following steps: First, mining and cutting works. In order to reduce the amount of mining work, a mining system without slopes is adopted, and the scraper is equipped with a short shaft from the middle section Pull it to the level of the bottom layer of the panel, and then construct the cutting roadway (including the mining roadway) across the entire panel area, and simultaneously construct the veins from the bottom wall cutting roadway to the upper wall, and carry out the bottom expansion work according to the width of the designed approach. Between several approaches, strip-shaped ore pillars are reserved between each approach to effectively support the roof. When expanding ...

Problems solved by technology

Using this method to release water, the speed of water discharge is slow. After each filling, the water discharge time generally takes 1 day before the second filling work can be carried out. A stope needs 3-4 times of filling, and the cumulative filling time (including the discharge time) water time) it usually takes about 6 days to carry out mining work, and the work efficiency is low
