In each stage of the mine excavation roadway operation, when rock strata or ore strata are cut by rock drilling machines such as an excavator, the generated dust amount is the largest, and the released toxic and harmful gas is the largest. The cutting work of rock strata or mineral layers in mines belongs to a normal state, so that the working environment in the mines is usually very severe, and the health of workers in the mines is seriously threatened by dust and toxic and harmful gases. The dustproof dust mask worn by the worker reduces the comfort level of the worker, and the dustproof effect of the dust mask is easy to lose efficacy.
The underground mining dustproof isolation device provided by the embodiment mainly aims to provide relatively clean and comfortable environments for workers, the workers can enter the dustproof isolation device when needing to rest, or some work is not necessarily completed by exposing to dust, and the workers can also enter the dustproof isolation device to complete the work.
The existing ventilation mode in the excavation roadway of the mine is press-in ventilation, namely a press-in fan is placed at a position where the air in the main roadway is relatively fresh, then a flexible air duct is connected to the press-in fan, and the flexible air duct directly conveys fresh air flow to an area of excavation operation in the excavation roadway. The ventilation mode mainly has the functions of blowing out dust generated when cutting rock strata or mineral layers to the outside of the tunneling roadway and continuously updating the wind flow in the tunneling roadway.
However, in the forced ventilation, the air flow in the flexible air duct is fresh air flow, and the fresh air flow in the flexible air duct becomes dirty air flow once entering the tunneling roadway, so that workers cannot breathe fresh air.
The mine is also provided with types of pneumatic machines, namely, high-pressure gas is used for providing power for the pneumatic machines, type of pneumatic pumps are used for converting fresh air flow on the ground into high-pressure gas firstly, and then the high-pressure gas is conveyed into a driving roadway by using high-pressure gas conveying pipes such as high-pressure rubber pipes and the like so as to provide power for the pneumatic machines in the driving roadway.
The used high-pressure gas of pneumatic machinery is fresh air current, and the dustproof isolating device that this embodiment provided can directly utilize current high-pressure gas transmission equipment in the mine, for the inside fresh air current of input of dustproof isolating device, satisfies the workman and needs.
When the dustproof isolation device is constructed in a driving tunnel, along with the propulsion of a working face in the driving tunnel, the working area of a worker is also in the straight-changing state, and the dustproof isolation device provided by the embodiment can be moved along with the propulsion of the driving working face in the driving tunnel, so that the worker can conveniently enter the isolation device at any time.
In view of the application, characteristics and various requirements of the dustproof isolation device in the above description, the following detailed description is made in terms of the shape, structure, material and the like of the dustproof isolation device, so that a person skilled in the art can understand the dustproof isolation device provided by the present embodiment and can conveniently implement the dustproof isolation device based on the understanding.
As shown in fig. 1 and 2, the underground mine dustproof isolation device provided by the embodiment comprises an isolation room 1 arranged in a mine roadway, an isolation space is formed in the isolation room 1, a room 2 is arranged on the isolation room 1, an air supply port 3 and an air exhaust port 4 are further arranged on the isolation room 1, the air supply port 3 is used for introducing fresh air from the ground into the isolation room 1, and the air exhaust port 4 is used for exhausting dirty air in the isolation room 1 into the mine roadway.
The dust-proof isolation device provided by the embodiment comprises an isolation room 1, the isolation room 1 is most different from a ground building in that the ground building is in a better environment, the ventilation of a special room is not needed, and people can have a good working environment and a good living environment, and the isolation room 1 in a mine is in an environment filled with dust, toxic and harmful gases, so that the isolation room 1 has to be supplied with air of a special room in order to enable workers to be in a relatively clean environment.
The isolation room 1 is mainly used for providing isolation spaces for workers to move or rest, the number of workers working in working areas in a driving roadway is which is 5-10, so that the number of people accommodated in the isolation space of the isolation room 1 can be referred to.
The isolation room 1 of the embodiment can also only contain persons or two persons, in this case, a plurality of isolation rooms 1 can be arranged near the same working area at the same time to meet the requirements of workers, and the single isolation room 1 has smaller floor area and is easier to move.
The width of the excavation roadway is between 2m and 5m, and machines such as rails and belt conveyors are usually arranged in the excavation roadway, so the size of the isolation room 1 is adapted to the residual size in the width direction of the roadway, and enough pedestrian passages are reserved between the isolation room 1 and other mechanical equipment.
The isolation room 1 can be in a cuboid shape, and when the isolation room 1 is placed, the length direction of the isolation room 1 can be along the length direction of a roadway, when the isolation room 1 is in a cuboid shape, on the isolation room 1 can be arranged on the side of the width direction of the isolation room 1. it can be understood that if the orientation of a room 2 arranged on the isolation room 1 is opposite to the flow direction of dirty air in the roadway, dirty air can easily enter the isolation room 1 when the room 2 is opened, therefore, the orientation of a room 2 arranged on the isolation room 1 can be the same as the flow direction of the dirty air in the roadway, and accordingly, can prevent the dirty air from entering the isolation room 1 to a certain extent.
The roof of the isolation room 1 can be triangular or arc-shaped, and part of dust can slide off from the triangular or arc-shaped roof by utilizing the gravity of the dust, so that the phenomenon that too much dust is collected on the roof of the isolation room 1 can be avoided.
Because the shape that steel frame construction formed is stable relatively, non-deformable, keep apart room 1 and can form steel frame construction earlier when the preparation, then install panel on steel frame construction, can assemble into isolation room 1 fast or, keep apart room 1 and can be folded cascade, if keep apart room 1 when the cuboid, can expand into planes with isolation room 1, it is more convenient that the plane moves after folding back.
The isolation room 1 provided by the embodiment can provide relatively clean environments for workers, and the isolation room 1 has requirements on the sealing performance due to the fact that dust in mine roadways is large, toxic and harmful gases are filled in the mine roadways, so that the materials selected for the isolation room 1 and the joints of the isolation room 1 need to meet the requirements on the sealing performance.
In addition, the isolation rooms 1 are made of different materials, which can cause differences in cost and performance of the isolation rooms 1.
For example, when the steel sheet was chooseed for use to the preparation material of isolation ward 1, because the intensity of steel sheet is high, the rock piece that the steel sheet can keep out tunnel top and fall occasionally avoids the workman to be injured by the rock piece pound. If a thicker steel plate is adopted, when accidents such as roof collapse and the like occur in the roadway, workers can avoid disasters in the isolation room 1. However, the increase in the thickness of the steel plate increases the manufacturing cost of the isolation room 1, and the weight of the isolation room 1 increases, which increases the difficulty of transition.
If the isolation house 1 is made of wood plates, the cost is lower than that of steel, but the strength of the wood plates is greatly different from that of the steel, and when accidents such as roof collapse occur, the protection performance is lower. On the premise of forming the basic frame of the isolation room 1, the isolation room 1 can also adopt plastic plates, rubber plates and other plates to be fixedly connected with the basic frame, and measures such as sticking sealing strips and the like are taken at the joints to meet the requirement of the sealing performance of the isolation room 1 in the embodiment.

In addition, the isolation room 1 is also provided with an exhaust port 4 for exhausting dirty air, and the exhaust port 4 and the air supply port 3 are matched with each other to enable the air pressure in the isolation room 1 to be in a normal range.
When a high-pressure gas pipeline is adopted to provide fresh air flow for the isolation room 1, air entering the air supply port 3 is positive pressure, namely the air pressure at the air supply port 3 is greater than normal air pressure; since the exhaust port 4 communicates with the mine tunnel, the air pressure at the exhaust port 4 is smaller than the air pressure at the air supply port 3, so that the dirty air at the exhaust port 4 is automatically discharged.
In the use of the isolation room 1, there may be a case where dirty air in the mine tunnel enters the isolation room 1 from the air outlet 4, and in the other , the position where a person breathes air in the isolation room 1 is relatively high in the isolation room 1, so the air supply port 3 may be provided at the upper part of the isolation room 1 and the air outlet 4 may be provided at the lower part of the isolation room 1, thereby forming a ventilation direction in which fresh air enters at the upper part and dirty air is discharged at the lower part in the isolation room 1.
