Application of Wet Spray Machine in Mine Greening
Environmental protection and green issues have always been highly valued by governments and the society. There are also a large number of mines in China, but many places have turned mountains into barren mountains for mining. The survey results show that the national mine development covers an area of 1.775 million hectares. The mine development area used is about 50.2%, the abandoned mine development covers about 45%, and the restored mine area is about 4.8%. At the end of 2014, the national mine greening project has completed 11% of the national total, and is completing 14.08% of the national total, and 74.94% of the green is not restored. China has great potential for regreening.
Wet spray machine is suitable for rocking, hard soil, sandy soil, barren land, acid soil, arid zone, coastal dam and other places where plant growth is difficult. It is used for highway slope greening and high-speed railway slope greening. , mine greening, ecological restoration, desert management and other projects, can also be used for irrigation, fertilization, spraying pesticides and other daily care and soil improvement work, one-time seed, fertilizer, soil improver, seed binder, moisturizer, Fiber-covered materials, orange stalks, yellow loam, red loam, sandy loam, clay, and some strongly differentiated shale soils are mixed organically, and the slurry material is uniformly sprayed in a large proportion, high concentration and extra-concentration.
As an environmental protection product for mine greening and green spraying, the application of wet spray machine will become more and more extensive. The wet spray machine greatly reduces the dust concentration outside the machine and outside the nozzle, and eliminates the harm to workers' health. When wet spraying, since the water-cement ratio is easy to control and the concrete is highly hydrated, the quality of the shotcrete can be greatly improved and the homogeneity of the concrete can be improved.
With the rapid development of the economy and society, China's capital construction has accelerated, and a large number of exposed slopes have been formed due to the implementation of construction projects such as transportation, water conservancy, mines and electric power. These bare slopes not only affect the ecological environment landscape, but also some hidden dangers of geological disasters, affecting the safety and stability of the main greening project. As a result, many places have begun to vigorously carry out slope greening.
The environmental protection significance of using the wet spray machine for greening the slope is very obvious. The greening of the slope can beautify the environment, conserve the water source, prevent soil erosion and landslide, and purify the air. For the stone slope, the environmental protection significance of the slope greening is particularly prominent.
