(1)Characteristics—The collected ore is loaded into the mine car in the transportation lane by the weight from the funnel, through the grid screen and the mine drainage gate. If the ore that has slipped from the discharge hopper has a large piece, it should be crushed on the sieve to be crushed, and the broken ore will be slid into the mine. (2) The size of the bottom structure—the height of the bottom column is 12-18 meters, and it is inclined by 2° to 3° to the secondary broken chamber according to the installed sieve. The heap of ore that slips out of the funnel should not exceed 2/3 of the total area of ​​the sieve. (3) Advantages of the bottom structure - 1 large mining capacity; 2 low cost of mining. (4) Disadvantages of the bottom structure - 1 The amount of work is large; 2 The amount of minerals in the pillar is large, accounting for 20-30% of the total ore of the ore. 3 When mining, the working conditions are bad. (5) Usage – Due to the many disadvantages and obvious, the mines at home and abroad are rarely used. The existing grid is mainly used for the retention of centralized ore deposits, to prevent the ore block from being too large and affecting the transport of ore. (1) Usage - This kind of bottom structure is mostly used in the shallow hole retention method. Because the shallow hole retention method has narrow veins and is not easy to produce large blocks (1.0 m or more), this method is often used. (2) Features - This bottom structure, the collected ore is directly slid from the funnel directly to the funnel gate, into the mine car in the transport lane, and a small amount of large pieces, directly in the funnel Secondary crushing. Therefore, the gate is often collapsed, affecting the normal mining work. (3) Bottom structure size - This bottom structure has a small height of 5 to 8 meters, and the funnel spacing is generally 5 to 7 meters (variation is 4 to 6 to 8 to 10 meters). (4) Advantages and Disadvantages - <Benefits>: The structure is simple, no mechanical equipment is needed, and the amount of bottom pillars is small. <Disadvantages>: The mine release capacity is low, and the maintenance work of the mine discharge leak gate is large. (1) Features - It uses the pit wood to support the transportation lanes and erect the funnel gates, thus replacing the ore bottom fence. (2) Advantages - Due to the use of artificial false bottoms, the ore recovery rate is improved and the recovery process is simplified. (3) Applicable conditions - Applicable to the steep slope and vein of the ore and surrounding rock. (The thick ore body is almost useless) (4) Mine bottom form - The false bottom form can be divided into two types of wing-shaped and flat bottom, each of which is divided into several forms.
