Abstract

The invention provides a ventilating system and a ventilating method used for long-distance roadway tunneling. The ventilating system comprises n sealed chambers, a plurality of ventilators and ventilating pipelines. The n sealed chambers are formed on the lateral walls of roadways along the tunneling direction of the roadways according to preset intervals, n is a natural number and is increased monotonically along the increasing of roadway tunneling distance, and an air inlet and an air outlet are respectively arranged in each sealing chamber. The plurality of ventilators are arranged at roadway openings and in each sealing chamber. The ventilating pipelines comprise a plurality of sections of continuous pipelines which are connected with the ventilator at the roadway openings and extend into the inside of a first chamber, are connected with the ventilator of the ith sealing chamber and extend into the inside of the i+1th sealing chamber, and are connected with the ventilator of nth sealing chamber and extend into the part nearby a roadway working plane, wherein i is an natural number and 1<=i<=n-1. During ventilation, each ventilator presses fresh air near the ventilator into the ventilating pipelines connected with the ventilator.

Description

technical field [0001] The invention relates to the field of roadway excavation, in particular to a ventilation system and a ventilation method used in long-distance roadway excavation. Background technique [0002] At present, with the in-depth development of underground mines and underground engineering construction, there are more and more long-distance roadway constructions. In the construction of long-distance roadway, with the advancement of roadway excavation work, the ventilation distance of the excavation operation face in the roadway is getting longer and longer, and the difficulty of ventilation is getting bigger and bigger. Therefore, the removal of gun smoke and dust generated during the excavation process and the support process requires longer and longer ventilation time, and the ventilation effect is getting worse and worse. Especially in recent years, in order to speed up the construction progress and improve the mechanization level of construction, a large...
