Downhole sludge discharging device

Abstract

The invention discloses a downhole sludge discharging device, comprising a prepared mining block and a water pump suction pipe, wherein one side of the prepared mining block is provided with a stopingmining block; a mining tunnel is arranged around the prepared mining block; one side, far away from the prepared mining block, of the stoping mining block is provided with a drain pipe; a ventilationpipe is arranged above the stoping mining block; drain pipes are arranged above the stoping mining block and the prepared mining block; a water tank is arranged below the stoping mining block; a water tank inlet pipe is arranged on the front surface of the water tank; a liquid level detector is arranged on one side in the water tank; and a water tank protection net is arranged, near the liquid level detector, of the upper part of the water tank. The water tank protection net conveniently protect workers who pass around the water tank, avoids the problem of safety accidents caused by the deepwater level in the water tank, and also conveniently clean ore falling into water, avoiding the problem that water storage in the water tank is influenced due to the inconvenience in cleaning stones falling into the water tank.

Description

technical field [0001] The invention belongs to the technical field of mining, and in particular relates to an underground mud discharge device. Background technique [0002] Mining engineering is divided into coal mines and non-coal mines. Mining (English name: oremining) is the technology and science of mining mineral resources from the earth's crust or surface. Generally refers to the mining of metal or non-metallic deposits. In a broad sense, mining also includes the mining and beneficiation of coal and oil. Its essence is a selective collection and handling process of materials. Mining industry is an important raw material extraction industry, such as metal ore is the main raw material of metallurgical industry, non-metallic ore is chemical raw material and building materials, coal and oil are important energy sources. Most ores need to be enriched by beneficiation before they can be used as industrial raw materials. [0003] The existing drainage device for mining i...

Problems solved by technology

[0004] The purpose of the present invention is to provide an underground mud discharge device to solve the problem that the existing mining drainage device proposed in the above-mentioned background technology has poor safety when used, and the staff is easy to fall into the water tank of the drainage device when not paying attention. Large ore falling into the water tank will easily affect the water storage capacity of the water tank, which is not convenient for the normal drainage of the mine, and it is not convenient for the workers to carry out the construction safely, and the direct one-time drainage method requires a large power of the water pump
