摘要： Provided is a blower installed at a manhole opening, with which it is possible to facilitate an entry or an exit of a worker or an import or an export of an article. The present invention provides a ventilation system comprising a frame and a single or a plurality of airflow generation means arranged at the frame, a direction of an airflow is adjusted so that the airflow generated from the airflow generation means flows along with a virtual axis penetrating a virtual surface which the frame is regarded as to periphery, and the airflow flows while swallowing up the surrounding air of the virtual axis, and an air volume more than two times of total fluid volume of the airflow is generated.

摘要： The present invention relates to an active pressurization system making use of a platform track area upper slab of an underground train station. A track area, where a fast train and a slow train pass through an underground train station, is divided into a fast-train running space and a slow-train running space by means of a partition wall. Formed in an upper slab of the train station, there are a first and a second air-stream out- and in-flow space respectively linking to the fast-train running space and the slow-train running space. The front end of the second air-stream out- and in-flow space is provided with a first port and a first damper, while the rear end is provided with a second port and a second damper. The second air-stream out- and in-flow space is provided with a third port for venting of the slow-train running space. The first air-stream out- and in-flow space is provided with a fourth port for venting of the fast-train running space. When a fast train is running, a control panel that receives a sensing signal input from a pressure sensor for sensing pressure ensures that, on the slow-train running space where there is no slow train waiting, the first and second ports are closed and the first and second dampers are open and the third port is open and on the fast-train running space the fourth port is open, while on the slow-train running space where there is a slow train waiting, the first and second ports are open and the first and second dampers are closed and an air supplying and venting fan is driven in such a way as to supply air to the slow-train running space where there is a slow train waiting. The present invention makes it possible to solve the problem of ringing in the ears of waiting passengers by providing the fast-train running space where fast trains pass through and the slow-train running space where slow trains either stop or pass through, and by actively adjusting the supply and venting of air.

摘要： This invention is a system for ventilating underground mines wherein each fan that ventilates a workplace or heading is installed behind a ventilation door in an access to a non-pressurised ventilation shaft (the intake vent shaft) and the air that returns from the workplaces and headings flows naturally to the surface. There are no surface ventilation fans and there is no separation of a primary and secondary ventilation circuit.

摘要： A mine ventilation structure used to block a passageway or to prevent mixture of ventilation air at the intersection of two passageways. The passageway has sidewalls and a ceiling. The ventilation structure is formed of panels, each of the panels having spaced apart wire grids with an insulation core. The grids are interconnected with strut wires passing through the insulation core and forming a truss system. A layer of concrete is applied as gunite or shotcrete to the panels embedding the strut wires and covering the wire grids. The layer of concrete extends beyond the margins of the ventilation structure onto the sidewalls and ceiling of the passageway forming a monolithic structure sealed in the passageway that is virtually impervious to air.

摘要： A preferred cutting head includes a first body having a manifold for containing high pressure fluid and an axis of rotation generally parallel to the borehole, a first plurality of mechanical bits disposed on the first body, a first plurality of nozzles disposed around the axis of rotation for spraying the high pressure fluid, and a plurality of tubes fluidly coupling the manifold and the first plurality of nozzles. On supplying high pressure fluid to the manifold and rotating the cutting head about the axis of rotation, the nozzles create a generally circular, overlapping pattern of high pressure fluid in front of the cutting head, the pattern of high pressure fluid being directed to cut the borehole independently of the mechanical bits.
