Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wellhead automatic spraying systems, and specifically to an automatic spraying system for the wellhead of a raise in an open-pit mine. Background Technique
[0002] The dust raising at the raise wellhead in an open-pit mine has an important impact on the mine operation environment and the health of practitioners. In the past, open-pit mines usually reduced the dust raising at the raise wellhead by using a water sprinkler truck or installing a fog cannon machine. However, the wind speed is generally high at the raise wellhead in an open-pit mine, and the water mist generated by the fog cannon is greatly affected by the wind direction and wind speed, and cannot effectively reduce the wellhead dust raising when the temperature is high and the wind speed is large. The water sprinkler truck has high water pressure and large flow rate, and can well inhibit the dust raising. However, the water carrying capacity of the water truck is limited, the mine production time is long, the water consumption for long-term fixed-point dust reduction is large, and it is also time-consuming and laborious. Moreover, in some remote areas of the mine, the water supply is insufficient.
