采矿等地下空间工程的稳定性研究一直是岩土工程界关注的热点问题。在分析、总结近年来国内外地下结构稳定性研究成果的基础上,尝试将数学解析法、经验类比法、相似模型试验法、数值模拟法以及现场监测法有机结合起来,提出研究地下人工结构稳定性的综合分析方法。将该综合分析方法应用到工程实践中,探讨在松软破碎矿岩条件下通过采矿环境再造技术实现矿石安全、高效回采的可行性。研究结果表明,该综合分析方法具有可操作性和实用性,可为此类复杂问题提供科学参考。
The stability research on underground space project such as mining is always a popular issue in geotechnical engineering. Based on the analysis and summary of the research achievement of underground structure stability at home and abroad in recent years, an organic combination of the mathematical analysis method, experience analogy method, similar model test method, a numerical simulation method and field monitoring method is tried; a comprehensive analysis method for researching on underground artificial structure stability is put forward. The comprehensive analysis method is applied to engineering practice: and realization of feasibility of mining safety and high-efficiency stoping through the mining environment under the condition of loose and fractured ore rock is discussed. The research result shows that this comprehensive evaluation method is feasible and practical, so as to provide scientific reference for such complicated problems.
