Abstract

A system and a method for using bacteria to strengthen cemented filling materials belong to the field of mine filling. The technology is to use the acid mine wastewater rich in bacteria in the filling material preparation process, improve the performance of the filling material and reduce environmental pollution. The bacteria enrichment system includes a bacteria enrichment tank, a pH value detection device, an oxidation-reduction potential detection device, a bacteria counting device, a dissolved oxygen detection device, etc., which can realize real-time monitoring and adjustment of the bacterial enrichment environment and real-time detection of the bacterial concentration. The mixing system includes a water pump, a mixing bucket, a mixing blade, a motor, etc., which can fully mix the bacterial solution and filling materials. The filling material monitoring system includes viscosity sensors, concentration sensors, electromagnetic flowmeters, computer centralized control data platform, etc., which can realize real-time monitoring and adjustment of filling material performance. The system is reasonable and convenient, and can effectively reduce the production of mine pit wastewater and reduce environmental pollution. Improve the performance of filling materials and reduce production costs.

Description

technical field [0001] The invention relates to the technical field of mine filling, in particular to a system and a method for using bacteria to strengthen cemented filling materials. Background technique [0002] The process of extracting valuable components from mineral resources produces a large amount of tailings, and increasing mining activities have resulted in a significant increase in tailings production. For example, there are now about 12,000 tailings ponds in China, and the total amount of tailings piles exceeds 10 billion tons, and the annual growth rate is 600 million tons. These tailings occupy a large area of ​​land and deteriorate the environment. In fact, the most common and economical method of dealing with tailings is surface accumulation. Normally, as the mining continues to go deeper into the ground, the tailings gradually accumulate and eventually form a tailings dam. Improper disposal of tailings has caused economic losses and environmental degrada...
