摘　　要：针对以往物理相似材料模拟中不能满足部分试验及工程需要的缺陷,研制新型的岩层结构运动演化数控机械模拟试验系统。详细介绍该试验系统研制的原理、主要结构和功能特点。通过室内试验验证,该系统具有操作方便、自动化程度高、试验过程稳定、数据精度较高、材料拆卸安装方便及重复性好等特点。数控机械模拟试验系统克服相似材料模拟试验存在的铺设麻烦、成型技术与成型质量难以控制、试验周期较长、材料不能重复使用、模型容易受外界因素影响等缺点。该试验系统可以直观展现采动覆岩结构形变演化特征、上覆岩层破裂突变与应力场之间的对应关系以及煤柱上方弹性变形能聚集与释放规律。According to the defects in physical similar material simulation test that cant meet some engineering requirement,the NC mechanical simulation testing system for deformation simulating the evolution of rock structure movement was developed.The development principles,main structures and function characteristics are given detailedly in this paper. The system can easily be operated,and has characteristics such as high automation,stable testing process,convenient disassembly and installation,good repeatability,which have been proved through laboratory test. The NC mechanical simulation testing system is superior to similar material simulation experiment for its laying difficulty,molding technology and forming quality is difficult to control,the long test cycle,materials can＇t be used repetitively,and is easily affected by external factors. The NC testing system can show the space structure evolution process of the overlying strata by mining,the corresponding relation between strata fracture mutations and stress field,the law of elastic deformation energy accumulation and release above the coal pillar intuitively.
