technical field

The invention relates to the technical field of mineral machinery, in particular to a filling system capable of automatically adjusting humidity.

Background technique

At present, in mining operations, the exploitation of underground resources continuously destroys the balance of the original underground material composition, groundwater flow field, and original rock stress field, and forms an underground goaf. When the mining operation process does not exceed the set control range, the operation process is safe; when the mining operation process is out of control and exceeds the set control range, such as roof fall, water inrush, surface subsidence, debris flow or Mine safety accidents such as surface water influx into underground mines and large-scale ground pressure activities. The occurrence of these safety accidents is closely related to the existence of gobs. If high-quality filling is carried out in the goaf during the mining operation, the above-mentioned safety accidents can be effectively prevented and controlled. empty area.

At present, when the tailings of the ore dressing plant are used to fill the underground goaf, the hydraulic filling method is usually used to directly transport the tailings with a volume concentration of 20-60% to the filling area. The method is simple and efficient, but it will cause the following adverse effects: 1. Due to the small particle size of the tailings, it takes a long time for the tailings filled in the goaf to settle and dry up to withstand a certain pressure, and the subsequent ore needs to be mined under the condition that the filling area can withstand a certain pressure. Therefore, the mining of the subsequent ore is hindered; 2. During the tailings filling process, a large amount of fine tailings flow into the underground water tank with the water flow, causing the underground water tank to silt up and destroy the underground drainage system of the mine. 3. The water in a large amount of tailings flows into the underground water tank along with the tailings, which increases the underground drainage and consumes a lot of electricity.

The above disadvantages can be avoided by using the dry filling method, but the current dry filling method generally uses mine trucks or other machinery to transport the dry filling material from the ground to fill the gob. Compared with the hydraulic filling method, the transportation efficiency is low.
