Abstract

The invention discloses a preparation method of a calcareous bare rock root riveting transition layer. The preparation method comprises the following steps that (1), calcareous sand, cement, porous minerals and bottom mud are uniformly mixed, then water is added, and stirring is carried out uniformly to obtain transition layer slurry; and (2), the transition layer slurry in the step (1) is sprayedto the surface of the mine. The preparation method can effectively solve the problems of prone dust raising and poor water retention capacity of the existing mine surface.

Description

technical field [0001] The invention relates to the technical field of on-mine restoration, in particular to a preparation method for a rivet root transition layer of travertine-based bare rock. Background technique [0002] With the development of science and technology, the consumption of mineral resources in various industries is increasing day by day. With the development of mineral resources, various environmental problems and contradictions are becoming more and more prominent. The development of mineral resources has brought about various environmental problems including vegetation destruction, water and soil erosion, and dust, all of which have had a serious impact on the surrounding production, life and environmental sanitation. [0003] There is a large amount of fine powder on the surface of the mine, which is very easy to cause dust; the heavy metal content in the fine powder is extremely high, and the fine powder on the surface of the mine is very easy to cause...
