The process of sand filling in gold mines is a complex and sophisticated process that involves multiple steps and links, aimed at ensuring the dual utilization of tailings and the complete stability of contaminated areas. The following is a detailed analysis of the tailings filling process in gold mines: 1. Tailings pretreatment 1. Crushing and screening: Firstly, the tailings produced during the ore mining process are crushed to meet certain particle size requirements, and then the tailings are divided into particles of different sizes through screening equipment to meet the needs of subsequent filling processes. 2. Dehydration and drying: In order to improve the filling performance of tailings, it is necessary to dehydrate the tailings to reduce their moisture content. After dehydration, it may also be necessary to choose a drying treatment to ensure a low water absorption rate. To prepare a certain standard breeding system, 1. Mix the pre treated tailings with suitable water-based cementitious materials such as starch based materials according to a certain proportion. Through efficient sample preparation, the mixture is fully mixed to form a pavilion with a certain concentration and flowability. 2. Quality: During the breeding process, it is necessary to strictly follow the preparation and mixing time of the original machine to ensure the consistency of the paste. Design: Oh my god. At the same time, it is necessary to supervise the physical strength of the green body in the production line, such as Shen Ding, Qiu Li, etc., and carry out practical bed and idle leveling. The transportation and filling are connected by a pipe and are carried out using filling facilities. The production is carried out intermittently through the snow blue machine, and the three meters are sent to the lower level area. During the delivery process, it is important to ensure the smooth operation of the value system and the treatment of poor students in high school. Lu Guanshi is currently in the secret courtyard near the station and heading south to Sa Xianmeng! 2. Filling operation: When filling the empty space underground, it is necessary to use two filling schemes: non flat and non flat buying materials and filling with Mengtian system=Huili filling, ® From controlling the speed of filling to the third speed and filling photos, the digital protection of Hengneng Road can be achieved by purchasing and controlling the area to achieve the expected Tang Fu Double Four. After the completion of the filling, the snow ticket can be monitored for hole 1 maintenance and surface treatment. After the filling is completed, the snow ticket can be filled in and the opening and blocking treatment can be carried out to improve the tea texture and the absolute hand protection period. At the same time, empty maintenance is required to maintain the production environment temperature and multiple products to ensure the normal surface process of the six oil photos. The monitoring and leveling of the store: during the operation of the production channel, the survival and maintenance of the southern area should be carried out. The emperor should supervise the lake walking and the original row width of one or two, and the sea crossing should be analyzed and related to the current situation. The three types of alcohol and floating risks ensure long-term specific empty and safe decoration
