Problems solved by technology

[0004] Due to the different types of solid waste and industrial waste slag in the mining area, in order to ensure that the strength of the obtained filling body can meet the needs of mining, a large number of experiments are required to determine the proportion of cementitious materials before mining. This process takes a long time. low efficiency

Embodiment 1

[0034] Example 1 Proportion decision of cementitious materials for mining in Sijiaying Iron Mine

[0035] The Sijiaying mining area is located in the eastern Jidong Plain. Not only is it difficult to acquire land for the tailings pond, but also the surface does not allow subsidence. Therefore, the full tailings filling method is adopted for resource mining. In order to solve the economic benefit problem of iron ore full tailings filling mining, it is urgent to carry out the optimal decision-making of the ratio of iron ore full tailings filling cementitious materials. For this reason, adopt the inventive method to carry out the decision-making of the proportioning of cementitious material for mining with full tailings filling of Sijiaying Iron Mine, concrete implementation steps are as follows:

[0036] (1) Investigation and analysis of physical and chemical characteristics of full tailings filling material and industrial waste residue in Sijiaying Iron Mine, and selection of...

Embodiment 2

[0057] Example 2 Decision-making on the ratio of gelling agent for mixed filling materials of full tailings and rod frosted sand in Jinchuan Nickel Mine

[0058] The cemented filling method of Jinchuan Nickel Mine has always used rod abrasive filling. The mining cost of filling is high, and the whole tailings of the ore dressing cannot be used and are piled up in large quantities. The above problems can be solved by using the mixed filling material of rod scrub and full tailing sand. For this reason, adopt the inventive method to carry out the decision-making of the proportioning of Jinchuan Nickel Mine full tailings and rod frosted mixed filler filling cementitious material for mining, concrete implementation steps are as follows:

[0059] (1) Investigation and analysis of physical and chemical characteristics of full tailings and rod sand mixed filling materials and industrial waste residues in Jinchuan Nickel Mine, and selection of cementitious materials.

Abstract

The invention discloses a mining filling cementing material ratio decision-making method, relating to the field of mining technology. A uniform design experiment method and an orthogonal experiment are adopted to obtain orthogonal experiment data that the strength of a filling body is changed along with the change of ratio of gelatinizing agent; an artificial neural network model is adopted to perform information extension on finite orthogonal experiment data; a statistical regression and parameter fitting method is adopted to establish the function relationship of the cementing material ratio and the strength of the filling body, the strength of the filling body is used as an optimization object and the value range of the gelatinizing agent material is used as a constraint condition to establish a cementing material ratio optimization model; the optimization model is solved to obtain the optimal cementing material ratio scheme. The decision-making method can utilize the finite experiment data to rapidly and accurately obtain the optimal ratio of the cementing material meeting the requirement of the strength of the filling body.

Description

technical field [0001] The invention relates to a decision-making method for the ratio of cementitious materials for mining, in particular to a decision-making method for the ratio of cementitious materials for mining prepared from industrial waste residues. Background technique [0002] Industrial production and resource development are accompanied by the discharge of a large amount of industrial waste residue and solid waste. A large number of industrial waste residues and solid wastes are piled up, which not only takes up a lot of land, but also pollutes the environment. [0003] In recent years, the filling and filling mining method, which is mainly used in the mining of non-ferrous metal deposits, has been more and more applied in iron ore mines, and it is also the only way for future resource development. The filling method mining mainly involves the selection of filling aggregate and cementitious material, the proportion of materials and the preparation of slurry. A...
