The embodiment of the invention discloses a mining method of manganese ore. The mining method includes the steps that a mining district is arranged, the mining district is divided along the strike ofan ore body, return air rise and track rise are arranged, a crosscut is arranged between the return air rise and the track rise, and the return air rise with the track rise are communicated through the crosscut; a working face is arranged, a headentry, a tailentry and a middle lane are arranged on the working face, wherein the middle lane is arranged between the headentry and the tailentry, and the middle lane, the headentry and the tailentry are arranged at the same layer position of the ore body; mining equipment is arranged, a scraper conveyor is installed at an open-off cut position, a mining-loading machine is installed at one end of the scraper conveyor, a transfer machine and a crusher are installed on the headentry, and a drilling machine is arranged on the middle lane; and an orebreaking manner is determined, and the mining-loading machine is adopted on the working face for mechanical ore breaking; when the hardness of the ore body is greater than the set value, loosing-blasting holes are formed in the two sides of the middle lane, and the ore body is loosened by adopting explosive blasting; and ore is transferred from the working face to a ground ore bin.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of mining of ore bodies, in particular to a method for mining manganese ore, especially a method for continuous transport and mining of manganese ore with long-wall retaining roadway mechanized falling ore. Background technique [0002] Manganese ore is one of the important resources for steelmaking. At present, the mining methods of manganese ore include empty field method, filling method and caving method. The open-field method adopts the comprehensive mining method, the room-and-pillar mining method and the ore-retaining mining method according to the different ore body occurrence conditions. The caving method includes wall caving mining method, layered caving mining method and segmental caving mining method. Filling methods include water-sand filling mining method and wall-cutting filling mining method. These mining methods all need to leave a large number of ore pillars, and ...
