Problems solved by technology

However, engineering ventilation is mostly a temporary project and is often not taken seriously, so it is one of the important reasons for underground engineering accidents
[0003] The use of rigid ventilation pipes is expensive, heavy, inconvenient for construction, and the ventilation quality is poor due to short pipe joints
However, the existing soft ventilation pipes are mostly made of artificial leather; the material strength is low, the manufacturing rate is large, the wind pressure loss is large, and the ventilation distance is short; Extremely poor environmental conditions for underground engineering

Embodiment Construction

[0019] The long-distance, large-diameter ventilation hose (abbreviation: ventilation hose) in the present invention is a textile cylindrical fabric. Wherein, the textile cylindrical fabric is a cylindrical fabric woven with high-strength synthetic fiber filaments, wherein the synthetic fibers can be various existing fibers, such as: polyamide fiber, polyester fiber, polyester fiber, etc. Acrylonitrile fiber, polypropylene fiber, etc.; the cylindrical fabric is a cylindrical seamless fabric woven by a circular loom. This ventilation hose has light weight (200-400 g / m 2 ), high material strength, long single-section air duct (up to 100 meters), few joints, small fan leakage rate, and good ventilation quality; it is suitable for temporary or short-term ventilation in underground mines. For the above-mentioned ventilation hose, the required air volume and wind pressure can be calculated according to the engineering needs, and the diameter of the ventilation pipe can be determined...

Abstract

The invention discloses a long distance and large diameter vent hose, an installation method thereof and a ventilation system, which aim at solving the problems of complex structure, high cost and the like of the prior art. The vent hose is a textile tubular fabric. The ventilation system comprises at least one blower station which is arranged outside an underground work and the vent hose which is used for communicating the blower station and the working surface of the underground work, wherein, the vent hose is prepared from the textile tubular fabric. The vent hose is characterized in that: the vent hose is fixed on the internal wall of a laneway by using one net cord or a plurality of net cords, and both the products and method used have the advantages of light weight, convenient installation, longer single segment air duct, few connection points, quite low rate of air leakage, good ventilation quality, small ventilation resistance, energy conservation, and the like.

Description

technical field [0001] The invention relates to a long-distance, large-diameter ventilation hose, a method for installing the ventilation hose and a ventilation system. Background technique [0002] Safety accidents in underground mines occur frequently. The cause of the accident is complex, including mechanics, materials, equipment, technology, groundwater, gas, management and many other factors. Among them, underground engineering ventilation, especially long-distance ventilation, is a difficult problem in underground engineering. However, engineering ventilation is mostly a temporary project and is often not taken seriously, so it is one of the important reasons for underground engineering accidents. [0003] The use of rigid ventilation pipes is expensive, heavy, inconvenient for construction, and the ventilation quality is poor due to short pipe joints. However, the existing soft ventilation pipes are mostly made of artificial leather; the material strength is low, t...
