Embodiment

[0036] An intelligent dust control and dust suppression system is installed in a 2.5m high, 3.7m wide, and 50m long excavation roadway in a copper mine. The distances between the two side wall surfaces of the roadway 1 and the driving face 14 are 20m and 10m respectively. The water supply pipe 6 adopts a steel pipe with a nominal diameter of 15mm, and the water supply pressure is 2.5Mpa. According to the cross-sectional size of the tunneling roadway, a dust-proof and dust-suppressing net 10 covering the entire cross-section of the tunneling roadway is suspended on the section. The material of the dust-proof and dust-suppressing net 10 is stainless steel wire, and the mesh size is 5mm×5mm. Install a horizontal water pipe 8 with a nominal diameter of 15 mm on the top of the dust-proof and dust-suppressing net 10 along the width direction of the excavation roadway 1. According to the width of the excavation roadway 1, weld an atomizing pipe 8 vertically downward every 500 mm. 9 ...

Abstract

The invention discloses an intelligent dust control and suppression system for metal mine excavation roadway circulating ventilation. The intelligent dust control and suppression system is formed by combining a local ventilation system, a water supply system, a purification and dust removal system and an automatic control system. The local ventilation system comprises a compressed air fan (17-1), a compressed air cylinder (15), an air draft fan (17-2) and an air draft cylinder (16); the water supply system comprises a water pump, an electric valve, a Y-shaped filter, a water supply pipe and a vertical water pipe; the purification and dust removal system comprises a spraying device and a dust isolation and suppression net; the spraying device is composed of a transverse water pipe and a plurality of atomizing nozzles arranged on the transverse water pipe; and the automatic control system comprises a dust sensor (13), an infrared induction switch (11) and an electric control box (12). The intelligent dust control and suppression system has the beneficial effects of being easy to operate, reliable in running, high in practicability and the like, the problems that the excavation roadway ventilation system is low in air flow utilization rate and energy consumption is increased are effectively solved, and the phenomenon that dust further pollutes underground air flow and other operation places is avoided.

Description

technical field [0001] The invention belongs to the technical field of ventilation and dust removal for excavation tunnels in underground mines, in particular to a dust control and dust suppression system for excavation tunnels in metal mines, and is particularly suitable for application in circulation and ventilation systems for excavation tunnels in metal mines. Background technique [0002] The ventilation and dust removal effect of the mine directly affect the safety of the mine and miners, and also directly affect the sustainable development of mining enterprises. At present, most of the mining of metal mines in my country has entered deep mining, and the problems of underground ventilation and dust removal have become very difficult. Mine excavation roadways, especially single-head excavation roadways, have no penetrating air flow, resulting in poor ventilation and easy accumulation of dust. If only the ventilation of the excavation roadway is considered, and the dust ...
