Abstract: In response to the actual demand that lifting capacity is larger during the second phase construction of Yuanzigou Coal Mine after the air shaft is exactly grounded. We propose a large mine mixing temporary reequipping technology after comprehensive analysis of the depth of coal seam, shaft and tunnel engineering construction, existing technology and equipment and construction schedule. Using the double cafe and the double skip mixed lifting way, various systems formed simultaneously during the vertical mixing temporary re-equipping period. The actual application shows that this technology can shorten the construction period, ensure the mine production schedule, create significant economic benefits for Yuanzigou Coal Mine. After one month trial operation, the entire system is safe and reliable and receives the expected results.
