Description
Technical Field
The invention relates to a filling material containing lepidolite slag, a preparation method thereof and application thereof in mine filling, belonging to the technical field of filling by using the lepidolite slag.
Background
The lithium resources in China are rich in types and large in reserves, wherein the lithium resources in Jiangxi province are mainly lepidolite ores, the reserve of the lepidolite ores is 71.03 ten thousand tons, and the lepidolite lithium mineral is one of the largest lithium resources mined and utilized in China. With the rapid development of new industries, the demand of China for lithium salts is rapidly increased year by year, and the discharge amount of lithium slag is increased day by day. According to statistics, about 8-10 t of lepidolite slag is generated when 1t of lithium salt is produced, a large amount of accumulated lepidolite slag occupies land on one hand, secondary pollution is caused to the environment on the other hand, and along with the large amount of exploitation of lepidolite, overlying rock layers of lepidolite mines collapse to cause large-range collapse of the earth surface, so that ground buildings, railways, roads, rivers and the like are seriously damaged. The mine filling mining is an important technical means of high mining efficiency, safety and green construction of modern mines in China, and can play multiple roles of comprehensively solving the problem of effective utilization of solid wastes of mines, improving the mining rate of ore resources and protecting the surface ecological environment.
The materials currently used for mine filling mainly comprise high-molecular foaming filling materials, inorganic powder foaming filling materials, foaming cement slurry filling materials mainly comprising cement and fly ash, high-water filling materials and the like. The high polymer foaming filling material has the advantages of rapid reaction, large foaming times, simple and rapid construction, less single materials, but the problems of incapability of pumping in a long distance, high curing temperature, potential safety hazard, toxic substances such as formaldehyde, phenol and the like, low compressive strength and the like. The inorganic powder foaming filling material has the characteristics of good pumping performance, long-distance pumping, simple and convenient operation and excellent sealing property, but has high early investment cost, long foaming time and low compressive strength, and can not meet the actual use requirement of mine filling. The foaming cement slurry filling material mainly comprising cement and fly ash uses cement, fly ash and other materials in large quantity, has wide material source, low cost and excellent long-distance pumping performance, the compressive strength of slurry can reach about 1MPa, but the equipment investment is large, the dust pollution is serious, grouting pipelines need to be pre-buried for filling waste roadways, and sectional filling and sectional grout stopping walls are designed, so the flexibility is not enough, and the foaming cement slurry filling material is not suitable for small-range filling. The high-water filling material has the advantages of good pumping performance, short rapid hardening time, capability of utilizing slag as a raw material and the like, can fully meet the requirements of the layered mining technology, can fill and treat large goafs quickly, can utilize waste slag, reduces the pollution to the land environment, reduces the material cost, and is widely applied to the field of mine filling. The invention patents CN107417228A and CN105152612A respectively disclose a fly ash-doped high-water filling material and a gravel-doped high-water filling material, which reduce the cost of the filling material, but the final setting strength needs to be further improved (the final setting strength of the former 28d is only 540kPa, and the final setting strength of the latter is only 755-1140 kPa). The invention patents CN108706922A and CN101792291A respectively disclose a high water swelling filling material which has the characteristics of good fluidity and high final setting strength, but the initial setting time is long (the initial setting time of the former is 67-187 min; the initial setting time of the latter is 90-120 min), and the slurry accumulation capacity is poor. At present, China has little research on high-water filling materials, and the existing high-water filling materials generally have the problems of long initial setting time, low slurry viscosity and easy flowing in the filling process, so that accurate consolidation in a specified area is difficult to realize, and inconvenience is brought to filling construction and subsequent mining. When the slag is doped to prepare a high-water material, the quality problems of poor consolidation performance and reduced mechanical property of the material also exist.
