Problems solved by technology
[0003] Existing ventilation equipment often has the following problems when performing ventilation operations inside the mine: a: When the existing ventilation equipment performs ventilation operations inside the mine, there is often a large amount of dust inside the mine, thereby performing ventilation operations for a long time Finally, the air intake is often blocked by a large amount of dust, which affects the ventilation effect; b: when the existing mine ventilation equipment is used for ventilation inside the mine, it is often buried in the sudden interior to connect the mine and the surface to form a ventilation system. When the ventilation pipe is used for a long time due to extrusion, the ventilation pipe will often be deformed

The invention relates to a ventilating device for underground mine mining roadway, which includes a support set and a recovery set. The support set is installed inside the soil, and the support set is provided with a recovery set. The present invention can solve the problem of the existing ventilation equipment performing ventilation operations inside the mine The following problems often exist: a: Existing mine ventilation equipment often has a large amount of dust inside the mine when performing ventilation operations inside the mine, so after a long period of ventilation operations, the air inlet is often blocked by a large amount of dust, Thereby affecting the ventilation effect; b: when the existing mine ventilation equipment is used for ventilation inside the mine, it is often buried inside to connect the mine and the ground surface to form a through hole. The pressure often causes the deformation of the ventilation pipe.
Description
technical field [0001] The invention relates to the technical field of roadway ventilation, in particular to an underground mine mining roadway ventilation device. Background technique [0002] Mining is a basic industry for economic and social development. With the development of economic globalization and the establishment and improvement of the WTO mechanism, the globalization trend of mineral resource allocation has become extremely obvious. The international mineral resource competition is becoming increasingly fierce. It is carried out underground, and the underground often contains toxic gas, which poses a serious threat to the health of employees. At the same time, in order to ensure that there is no harmful gas and sufficient air inside the mine, the mine is often uniform during mineral mining. It is arranged to ventilate the inside of the mine through pipelines, but the existing mine ventilation equipment still has certain deficiencies when performing ventilation o...
