(1) The selection of the type of the leakage gate shall meet the following requirements: (1) Simple and easy to use; (2) sturdy and durable, production safety; (3) Appropriate specifications (in accordance with the selected mine car). (2) Factors affecting the selection of the leakage gate: (1) The amount of ore mining and the length of use; (2) the intensity of ore discharge; (3) ore block size and shape; (4) Mine car specifications and volume; (5) Transportation lane specifications and support methods. (3) The composition and size of the mine leakage gate: (1) Dip floor inclination angle χ = 30o ~ 50o It is determined by the ore block. When the ore block is large, χ=30o～40o, when the ore is more than 注=40o～50o. Dry ore, the horns can be smaller, and the horns can be larger. (3) The end of the leaking bottom plate extends into the mine car by 150 to 200 mm and is higher than the mine car by 200 mm. (4) The width of the leak is determined by the length of the mine car and the degree of ore. The mine car should be facing the leak, not moving the position, filling the mine car once, and the width of the leak is (3 to 4) times the width of the (general) qualified block. (4) Types of leakage gates (1) The gate of the board leak. ①gate gate available quality cross-board, garden wooden or metal stick. 2 Such a gate has a simple structure, is easy to manufacture, and is easy to install. 3 However, the production has little solution, small amount of mining, high labor intensity, poor working conditions, slow loading speed and poor safety. (2) Fan gate: 1 Wide application range, simple gate, standardized components, easy to open and close, fast loading, safe work, not easy to mine (non-metallic mines). (3) Finger gate 1 Large metal mines are used more. The mining capacity is large and the operation is convenient. ② leaky Fines (e.g. temple iron ore used). (4) Chain gates. 1 The structure is simple in operation, reliable in operation, sturdy and durable, and has a large mining capacity. It is not easy to leak powder ore. 2 When the water is large, it is easy to leak and run. 3 More applications (including iron ore, Changling mine). (5) Vibration discharge machine mine release gate 1) The use of vibrating ore concentrating machine for mine has been used in China. At present, China is mainly used for ore mining at the lower mouth of the flow well. (Not yet used in the mining below; individual mines as of the beginning of the test Kaiyang phosphate mines in the whole test.). Our Xiaoxinancha, Yang stick 2 mine, Zhongtiaoshan colored in the company Hujiayu copper ore mines are used in the stream below, to good effect. 2) Advantages: 1 It transitions the intermittent gravity from the ore to the continuous forced ore, which changes the ore flow and expands the flow range of the ore discharge, thus effectively improving the ore-extracting conditions. Due to the vibrational ore release, the size of the ore discharge can be large, and the number of times the large block catches the leak is small. The amount of secondary crushing work has dropped significantly. Thereby, the ore-removing intensity and the labor productivity of the miners are increased (the ore-intensification intensity is increased by 5 to 10 times than that during gravity ore mining). 3 It fundamentally simplifies the bottom structure of the nugget. The amount of bottom pillars and mining work is small, and the maintenance cost of the roadway is low. 4 The mining work can be started to be manually controlled, and the mining area can be discharged, transported and loaded to achieve continuous operation, creating conditions for continuous underground operation. 5 Due to the controllability of vibrational ore mining, concentration of mining operations and mining enhancement, the operating conditions and working conditions are improved. 6 Due to the large capacity of the vibrating ore bin, the time for each mine to be filled is reduced. If you install a mine car that meets 2m 3 , you only need 7 to 8 seconds. 3) Disadvantages: 1 The equipment is cumbersome, and it is inconvenient to install and move. 2 If there is no continuous moving, transporting and equipment matching, the equipment utilization rate is low; 3 The requirements for one-time crushing are stricter. 4 The mining volume required for mining blasting is large (the use of large flow wells is appropriate). 4) Comparison of the vibration gate and the wind gate

(2) The inclination angle of the top plate of the leakage (also called the ore angle) should be such that β ≤ ore has a natural angle of repose.
Mine leakage gate structure
The handling equipment pours most of the ore into the flow well, and installs the discharge gate at the lower mouth of the flow well. The structural form of the gate directly affects the efficiency of the mining. It is necessary to study it.
