the location of the locations of the mine anemometers and requirements

air measuring station: measure through the air, the surface is smooth, a flat roadway section neat.

to accurately grasp the mine always in and out of the air volume and a workplace air whether meet the requirements, master the wind speed is in line with the provisions of the openings, grasp the condition of air leakage in mine, according to 'regulations' regulation, each mine must build system of wind, a comprehensive wind every ten days. Locations in all major wind location to set up the anemometers. Locations

anemometers must meet the following requirements:

( 1) Should be the total of the mine ventilation, total return, every level and the wing's total return air, into the wind, the mining area and the locations with the wind inlet and return air even set the site of the anemometers, but avoid repeat Settings.

( 2) Air measuring station should be located in a flat in the roadway, within the scope of its 10 m and after can not have romantic cross, cross section changes, obstacles and turn local resistance, etc.

( 3) Locations if anemometers is located in the cross section of roadway is not neat, its four walls should use other material lining is fixed shape section, shall not be less than 4 m length, and a smooth wall closely don't air leakage.

( 4) Mining face without fixed locations of anemometers, but must choose along with the working face advancing support in good condition, no local resistance before and after the wind section.

( 5) Air measuring station should be hanging wind records, records on a board locations indicated anemometers broken area, average wind speed, air velocity, air temperature, atmospheric pressure, determination of gas and CO2 concentration, dates, and people.

what basic requirements shall be met for the locations of the mine anemometers?

1 locations, anemometers must build with incombustible material;

2 locations, anemometers and roadway within 10 m straight, bend and roadway roof high risk area;

3 locations, anemometers shall not be less than 4 m length, cross section is flat convex concave ( 1 square meter range is not more than 1 mm) 95% of the roadway cross section, the section should not be less than the original.

4 some locations, anemometers must level off, the wall of the ear is epidemic. 5, in a wooden shack, iron shed supporting roadway locations to build anemometers should be the supporting all masked with smooth material.
