矿山治水改性粘土浆高压固结机理研究与应用

基于因地制宜、绿色环保的要求,矿山帷幕注浆领域越来越多采用粘土类注浆材料,粘土类注浆材料的非工业成品特点使之在性能上与传统注浆材料具有较大差异。为了开展非工业成品注浆材料固结机理研究,建设了专门的注浆材料高压固结装置,并在此基础进行了相应试验。试验结果表明,高压注浆状态下,给定配比改性粘土浆液固结时间约为110min,固结体结构为复合结构形式,根据此结果计算注浆浆液扩散半径为纯水泥浆液3.375倍,此研究结果在现场工业试验中得到了验证。该试验装置、试验方法及研究结果为改进现有注浆工艺提供了技术支撑,为帷幕注浆领域新材料研究与应用提供了借鉴。

Research and application of high pressure consolidation mechanism of mine watercontrol modified clay pulp

Based on the requirements of local conditions and environmental protection, more and more clay grouting materials are used in the field of mine curtain grouting. The characteristics of non-industrial grouting materials make them different from traditional grouting materials in performance. In order to study the consolidation mechanism of non-industrial finished grouting materials, a special high pressure consolidation device for grouting materials was built, and the corresponding tests were carried out on this basis. The test results show that the consolidation time of the given ratio modified clay slurry is about 110 min, and the consolidation structure is a composite structure. According to the results, the diffusion radius of the grouting slurry is 3.375 times that of the pure cement slurry. The results were verified in field industrial experiments. The test device, test method and research results provide technical support for improving the existing grouting process, and provide reference for the research and application of new materials in the field of curtain grouting
