High Elevation Transmission Technology with Photoelectric Distance Measuring Instrument Applied to Mining Block Survey
WANG Jin-hai
Abstract：During the elevation measuring in the construction of No.2141 coal transportation inclined gateway in No.6 Mine of Hebi Coal Industrial Company ,a photoelectric distance measuring instrument was applied .With the high elevation transmission of No.2141 coal bunker ,the high elevation introduc-tion accuracy and efficiency ware improved and the labor intensity was reduced with a satisfactory effect .After the gateway was run-through ,a gateway waist line error was 0.100m ,which could meet the requirements of the mine production and technology.Due to high accuracy of the run-through ,no repair work would be required for the gateway.
