The main diameter of Henan Chaohua mine is 4.5m in diameter and 289m in depth (including 3m water nest). The temporary wellbore modification equipment includes a pair of lt temporary bicycle cages, eight rope lanes and other pipelines as shown in FIG. 1. The conversion work was undertaken by the electromechanical team in the work area of three coal mines in Henan Coal Mine.
