Abstract

The invention provides an arrangement method of a ventilating and dust-removing system for the excavation tunnel, and includes a boring machine, a belt feeding machine, a belt transshipment device, a dust-removing device, and a ventilating device. The boring machine is connected with the belt transshipment. The transshipment device is set on the belt feeding machine, and the negative pressure wind cylinder of the ventilating device is hung on the tunnel and connected with a fan in a hooping method. Two positive pressure wind cylinders are arranged on the ventilating device, one positive pressure wind cylinder is connected with a fan and a dust catcher in the hooping method; the other positive pressure wind cylinder is connected with a cyclone in the hooping method and is hung on the tunnel. The dust catcher of the dust-removing device is set up on a dust catcher supporting device. The dust-removing device is arranged on a position 20 to 40 meters behind the boring machine, and the negative pressure wind cylinder is connected at a position 3 to 5 meters apart from and opposing the drivage face, fresh air is pressed in by the positive pressure wind cylinder, and the outlet is 15 to 35 apart from and opposing the drivage face. The ventilation arrangement of the method is rational and safe, the movement is convenient, the operation is simple, the dust removing effect is good, the water consumption is low, and the cost is low.

Description

Technical field: [0001] The invention relates to a method for arranging a ventilation and dust removal system, in particular to a method for arranging a ventilation and dust removal system for an excavation roadway which is suitable for excavation of mine roadways and tunnels of highways, railways and subways and where dust sources are concentrated. Background technique: [0002] Dust is one of the main natural disasters in mine excavation roadways, highways, railways, and subway tunnels. With the continuous improvement of the level of mechanization, the amount of dust generated is increasing. According to actual measurements, the dust concentration during machine excavation is as high as 1000- 3000mg / m 3 , and the degree of dispersion is high, among which respirable dust with a particle size of less than 7 μm accounts for more than 85%, which seriously threatens the safety and health of on-site workers. At present, there are many types of dust removal equipment in China, b...
