The main cause of collapse in dumps 1. The selection of the dump site is unreasonable and the basement is weak; Second, the science is not discharged according to the design, and the single step stacking is too high; Third, the unloading process is unreasonable, and the rock and soil are mixed; Fourth, the interception and interception facilities and the quality of the project are not relevant; 5. The drainage and drainage facilities are not sound; 6. The quarrying of the slope and the failure of the soil to destroy the slope; 7. Induced accidents such as heavy rains and earthquakes; Eight, illegal command, illegal operation; 9. The collapse caused by the gun vibration; 10. There is no survey, no formal design, no planning in the dumping site, and many safety debts have caused the slope of the dump to collapse; Strictly prevent slope collapse accident First, it must be layered and mined from top to bottom according to the design, and ensure that the slope parameters meet the design specifications. Strictly according to the design, the top-down step-by-step layer mining is conducive to the stability of the stop slope, improve working conditions, and reduce the number of people injured by rolling stones; The slope parameters must be strictly controlled according to the design to ensure that the parameters such as step height, slope angle, safety platform width and final slope angle meet the design requirements. Mining is strictly prohibited. Umbrellas and voids are strictly prohibited on the working surface. Blasting is carried out strictly according to the design, and reasonable blasting technology is used to reduce the impact of blasting operations on the stability of the slope. The second is to strengthen staff training and strengthen slope safety inspection Strengthen safety training for employees and enhance the safety and self-protection capabilities of employees; It is necessary to establish a slope management and inspection and monitoring system, conduct regular safety inspections on slopes, monitor major parameters such as slope displacement, and find hidden dangers in a timely manner. Third, it is necessary to excavate according to the design and strengthen the management of the dumping site. Strict earth-moving operations, draining according to the design, to ensure that the dumping sequence, stage height, total stacking height, safety platform width, total slope angle and other parameters meet the design requirements; Strengthen daily inspections, check the soil dumping parameters, deformations, cracks, bottom drums, landslides, etc. at least once a week. During the rainy season, conduct inspections every day, make records, and report abnormalities to the higher-level units in a timely manner. And take effective control and treatment measures; It is strictly forbidden to violate the regulations. Enterprises should strengthen the management of dumps, delineate the scope of danger, and set up warning signs.
