This invention discloses a feedback adjustment method for void filling parameters based on the probability integral method, comprising: determining the allowable surface deformation threshold according to the distribution of surface protection objects and relevant specifications; designing several interval filling schemes based on the dip width, mining height, and preset filling rate of the filling area, determining the filling area width, void width, and filling height in each scheme, wherein the filling area and void are alternately arranged; calculating the surface deformation parameters corresponding to each filling scheme according to the probability integral method model, comparing the surface deformation parameters with the allowable surface deformation threshold, and selecting candidate schemes that meet the threshold requirements; performing iterative optimization calculations based on the candidate schemes with the goal of reducing the filling rate, determining the minimum filling rate that meets the allowable surface deformation threshold, and obtaining the optimized interval paste filling parameters. This invention can solve the problems of long processing time and insufficient gangue during existing paste filling mining processes.

This utility model relates to a storage tank, including a tank body, an air bladder disposed within the tank body, and an air pump for inflating and deflating the air bladder. Compared to existing technologies, the storage tank of this utility model can be used for the transportation of bulk, fine materials such as feed and cement raw materials, and for the automatic distribution of these materials during loading. During loading, the air pump periodically inflates and deflates the air bladder, causing it to continuously expand and contract, breaking the stable material accumulation state within the tank and redistributing the material to fill the gaps between the tank body and the material. This increases the tank's filling rate, allowing the storage tank to replace manual material handling, achieving automatic material distribution, improving loading efficiency, and avoiding the safety hazards and efficiency fluctuations associated with manual operation. Furthermore, in the transportation of bulk feed, using the storage tank of this utility model eliminates the need for additional disinfection of transport vehicles and ordinary storage tanks due to manual material handling, thereby reducing labor and disinfection costs during the material loading process.
