Method for determining constituents of soil at tailings mining area

Abstract

The invention discloses a method for determining constituents of soil at a tailings mining area. The method comprises the following steps: firstly, carrying out soil sampling; and secondly, determining the physical properties, the chemical properties and the biological constituents of the sampled soil. The soil sampling comprises the following specific processes: digging a soil profile at a sampling point; carrying out layering by the sizes of 0-5cm, 5-10cm, 10-20cm, 20-40cm and 40-60cm; and then carrying out layered sampling on the soil respectively with an aluminum box, an annular cutter and a soil bag. By the method for determining the constituents of the soil at the tailings mining area, reliable data can be provided for the improvement on the ecological environment of the tailings mining area, and therefore the method is beneficial for the sustainable development of society, economy and environment of the tailings mining area.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a method for measuring soil components in tailings mining areas. Background technique [0002] In most mining areas of our country, the massive mining of mineral resources not only promotes local economic development, but also brings serious ecological and environmental problems. First of all, in the process of mining mineral resources, the soil and vegetation on the ground surface were severely damaged, and at the same time, a large amount of solid waste such as tailings and gangue was generated to occupy and destroy land resources, which made the contradiction of more people and less land in our province more prominent; Secondly, due to the characteristics of loose tailings, poor shear resistance, and poor stability, the tailings dams and tailings mountains formed by a large amount of tailings have hidden dangers of collapse and landslides, which are a huge thr...

Problems solved by technology

First of all, in the process of mining mineral resources, the soil and vegetation on the ground surface were severely damaged, and at the same time, a large amount of solid waste such as tailings and gangue was generated to occupy and destroy land resources, which made the contradiction of more people and less land in our province more prominent; Secondly, due to the characteristics of loose tailings, poor shear resistance, and poor stability, the tailings dams and tailings mountains formed by a large amount of tailings have hidden dangers of collapse and landslides, which are a huge threat to the lives and property safety of local people. Thirdly, the loose matter formed in the mining process forms a large amount of dust under the action of wind, polluting the local air, water and soil, and deteriorating the ecological environment
