Low cost, high strength, China's successful research on mining new technology
Surface subsidence, environmental pollution, underground resource recovery efficiency is not high, frequent accidents at coal mines and other issues, has been plagued our country's mining industry. Recently, a major technological innovation called “paste-like filling technology†has passed expert appraisal. Experts said that the promotion and application of this new technology with independent intellectual property rights will help solve many problems that plague the mining industry in China. Relevant statistics show that China's land destroyed by mining has reached more than 40,000 square kilometers and is increasing at a rate of 200 square kilometers per year. The total coal pressure is 13.7 billion tons due to fear of surface subsidence. Filling the mined areas caused by mining with filling methods is the main way to solve the collapse. Since the early 60s of last century, cement cemented filling mining of metal mines in rapidly widely used, but because of the inherent drawbacks of cement and high costs, the impact of mining enterprises.
With national high requirement of indoor cleanliness control, test methold put forward by Good Manufacture Practice (GMP) and fully implementation of GMP, it is important for Air Conditioning manufacturer to control indoor air leakage ratio, suspended particles and contaminant concentration in medical industry.

It has been successfully researched by China University of Mining and Technology (Beijing), Tsinghua University, Beijing Lanzi Ningshi Technology Co., Ltd., and has been thoroughly verified by international and domestic large-scale mining companies. Low cost, good fluidity, convenient transportation, high filling strength and environmental protection have become significant advantages of this technology. According to experts, the cost of this technology is only 30% to 40% of the cost of cement cementing. The use of paste-like cement filling technology can also increase the mine recovery rate to over 90%, greatly extending the service life of the mine. In addition, this technology uses industrial waste as the main raw material, which is beneficial to the recycling of waste.
At present, the research group has successfully developed a special preparation, transportation and filling process system, forming a complete set of solutions to solve the filling problem from theory to technology to engineering application.
