【摘要】 化学注浆是解决难灌注地层和低压条件下的矿井水砂灾害防治的有效手段。在分析国内外研究现状的基础上,本文对这一问题的研究思路和关键问题进行了探讨,提出通过模拟实验、现场监测和理论分析,研究化学注浆在治理矿井溃砂地质灾害时浆液与水砂耦合作用的渗流场、化学场、温度场的特征,建立溃砂灾害产生及治理的工程地质模式,明确化学浆液在不同工程地质特性的含水砂层中劈裂、扩散、渗透的机理,采用现代传感和信息采集技术对注浆压力、注浆量、浆液扩散情况实施全程监控;研究浆液扩散的微观机理并发展注浆效果微观检验手段等研究内容,为有效防治矿井溃砂重大安全事故奠定理论基础。更多还原

【Abstract】 The chemical grouting is one of effective methods to treat mine quicksand in difficult grouting strata with low grouting pressure.The research ideas and key questions are proposed in this paper,they are as follows:simulation tests,in-situ monitoring and theoretical analysis will be adopted to study the characteristics of the field of seepage,chemistry and temperature in the coupled action between grouts and quicksand during the treatment of the quicksand hazards.The engineering geological model is established for the cause and treatment to realize the mechanism of fracture,spreading and seepage grouting of chemical grouts in various water - bearing sand layers with different engineering geological behaviors.The modern transducer and information collection techniques can be used in the monitoring of grout pressure,grout volume and grout spreading in whole cause of grouting.The micro mechanism of grout spreading will be studied and micro inspects method for grouting effect will be developed.The research will lay a foundation for prediction and treatment of the serious accident of mine quicksand.更多还原
