中文摘要

膏体充填技术是一种用于治理地下采空区和尾矿库的绿色采矿方法。膏体充填体在采场中的固化过程是热–水–力–化学多场性能共同作用的结果。目前，对膏体充填体多场性能的研究主要包括室内相似模拟实验、现场多场性能监测实验、多场性能耦合模型构建、多场性能数值模拟。由于难以在真实采场中研究膏体充填体的原位多场性能，目前针对膏体充填体的原位多场性能的研究大多采用数值模拟方法。通过对真实采场中的膏体充填体的不同条件(例如，养护环境、采场几何形状、排水条件以及有无充填挡墙和充填速率等因素)进行模拟，进一步研究膏体充填体的原位多场性能。本文总结了开展膏体充填体多场性能数值模拟所采用的数学模型，并列举了数值模拟在原位膏体充填体多场性能演化的工程应用实例。最后提出膏体充填体多场性能需要加强相关理论研究，形成基于膏体充填体的强度设计准则，开展膏体充填体多场性能的全域数值模拟，开发基于膏体充填体多场性能演化的安全预警技术，开发膏体充填体多场性能监测技术和监测设备的自动化和无线化，实现膏体充填体多场性能监测技术的应用和推广。

Abstract

Abstract

Cemented paste backfill (CPB) technology is a green mining method used to control underground goaves and tailings ponds. The curing process of CPB in the stope is the product of a thermo–hydro–mechanical–chemical multi-field performance interaction. At present, research on the multi-field performance of CPB mainly includes indoor similar simulation experiments, in-situ multi-field performance monitoring experiments, multi-field performance coupling model construction of CPB, and numerical simulation of the multi-field performance of CPB. Because it is hard to study the in-situ multi-field performance of CPB in the real stope, most current research on in-situ multi-field performance adopts the numerical simulation method. By simulating the conditions of CPB in the real stope (e.g., maintenance environment, stope geometry, drainage conditions, and barricade and backfilling rates), the multi-field performance of CPB is further studied. This paper summarizes the mathematical models employed in the numerical simulation and lists the engineering application cases of numerical simulation in the in-situ multi-field performance of CPB. Finally, it proposes that the multi-field performance of CPB needs to strengthen the theoretical study of multi-field performance, form the strength design criterion based on the multi-field performance of CPB, perform a full-range numerical simulation of the multi-field performance of CPB, develop a pre-warning technology for the CPB safety of CPB, develop automatic and wireless sensors for the multi-field performance monitoring of CPB, and realize the application and popularization of CPB monitoring technology.
