Application of multiple measuring techniques in the sectional construction of main inclined shaft in Shoushan No.1 Mine
In view of the characteristics of sectional construction of main inclined shaft in Shoushan No.1 Mine of Pingcoal Mine,such as long surveying wire and many surveying links,a number of measuring techniques were applied in the sectional construction through surveying of main inclined shaft.A unified coordinate system was established by determining the starting data up and down the shaft.The orientation was controlled by adding test gyro edges in sections,and the 15"class control wire was laid down to measure the Angle in the shaft from the edge of the gyroscope.The edge was measured according to the requirements of the"Coal Mine Measurement Regulations".The virtual double traverse measurement technology was used to improve the measurement accuracy,and the measurement method of repeated branch wire sectional round trip self-closing was used to check,which reduced the influence of the paired point error on the tunnel penetration.The successful applica-tion of this measurement technology has accumulated valuable experience for the penetration measure-ment of long distance main inclined shaft construction.
