Design of Construction Organization for Mine with Annual Production Over 10 Mt

Based on the complexity and uncertainty of the mine construction with an annual production of 10 Mt, in order to ensure the total mine construction perio d and construction quality, taking the mine roadway construction as the key and taking the surface building and the electromechanical equipment installation as the sup plementary principle, two construction organization design plans were provided. The heading speed of the mine rock roadway would be 100 m per month and the driving speed of the mine seam gateway would be 200 m per month.As for the second plan, the heading speed of the mine rock roadway would be 120 m per month and the dri ving speed of the mine seam gateway would be 550 m per month.Meanwhile there would be 10 driving faces in construction, including three seam gateways. With the co mprehensive demonstration and analysis on the construction schedule index, hoisting and transportation, the domestic technical status and other factors, the first plan would be more scientific and rational, the first plan was determined to guide the site construction operation.
