A flushing system and flushing method for flushing dust accumulated in mine roadways

Abstract

The invention discloses a flushing system and a flushing method for flushing dust accumulated in a mine roadway. The pipeline, the flushing pipeline includes an inner pipe and an outer pipe, and a plurality of connecting pipes are arranged between the inner pipe and the outer pipe. The connecting pipes include an inner pipe connecting pipe and an outer pipe connecting pipe, and the inner pipe connecting pipe communicates with the inner pipe. The connecting pipe of the inner pipe passes through the outer pipe to communicate with the connecting pipe of the outer pipe, and the connecting pipe of the outer pipe communicates with the water chamber, and the connecting pipes are equipped with electromagnetic valves; the two adjacent inner connecting pipes separate the water chamber for spraying. chamber, and the outer pipe is provided with a plurality of flushing nozzles corresponding to the spray chamber. It is a double-core casing that can wash away the dust accumulation in the roadway under the premise of realizing the function of transporting dust-proof water underground in coal mines, achieving the effect of "one pipe with multiple functions", avoiding the complexity of manually erecting water pipes to spray dust, sprinkler sprinklers, etc. chemical work.

Description

Technical field [0001] The invention relates to dust prevention in mine tunnels, in particular to a scouring system and a scouring method for scouring dust accumulated in mine tunnels. Background technique [0002] As an inevitable product of coal production and processing, mine dust is a serious threat to the safety of mine production and the physical and mental health of miners. At present, although the main roadways in coal mines in our country have adopted various dust prevention measures such as installing water pipes to manually flush dust, sprinkler dust removal, use dusting agents to catch dust, ventilate dust, etc., due to the steep slope of the mine’s uphill and downhill roadways , It is difficult to effectively scour the dust accumulation or sprinkler dust removal; especially the return air tunnel of the mine is not allowed to enter casually, and it is impossible to flush it in time, resulting in the dust accumulation thickness of several centimeters. Threatening the ...

Problems solved by technology

At present, although various dust prevention measures have been taken in the main roadways of coal mines in my country, such as installing water pipes to manually flush dust, sprinkler dust removal, using sticky dust agents to capture dust, and ventilation and dust removal, due to the large slope of the roadways going up and down the mountain , it is difficult to effectively carry out manual scouring of dust accumulation or sprinkler dust removal; especially since the return air tunnel of the mine is not allowed to enter casually, it is impossible to flush it in time, resulting in the thickness of the dust accumulation reaching several centimeters, which greatly Threat to mine safety production

According to the domestic and foreign research status of dust control in coal mine roadways, it can be known that dust removal in mine roadways is generally carried out manually or by sprinklers. Intelligent and automatic flushing of roadway dust
