分段空场嗣后充填采场结构参数优化试验与理论研究-采矿工程专业论文.docx

Ab Abstract PAGE PAGE III ANSYS software, and then adopted FLAC3D software to analyze the stability of the level pillars under the condition of static force and blasting load to obtain the numerical solution of level pillars’ s optimum dimensions . （6）Fixed the optimum dimensions of the level pillar in the copper mine by synthetic theoretical analysis and numerical calculation. （7）To reduce the permanent loss of the level pillars, numerically simulated the bottom of the room which transfer from the original design loose medium filling to cemented filling whose proportion is 1:4 , and optimized the distribution and height of the cemented filling. （8）Using the method of numerical simulation to prove and optimize some stope structure parameters such as the size of room and ore pillar、 stoping sequence, the distribution and height of cemented filling in the spacer pillar. Key words: sublevel openstope with subsequent filling method; Generalized Hoek-Brown Criterion; level pillar; optimization of stope structure parameters 江西理 江西理工大学硕士学位论文 目录 PAGE PAGE IV 目 录 摘 要 I Abstract II HYPERLINK \l _bookmark0 目 录 IV HYPERLINK \l _bookmark1 第一章 绪论 1 HYPERLINK \l _bookmark2 1.1 引言 1 HYPERLINK \l _bookmark3 1.2 国内外研究现状 1 HYPERLINK \l _bookmark4 1.2.1 采场结构参数优化研究 1 HYPERLINK \l _bookmark5 1.2.2 矿柱稳定性研究 2 HYPERLINK \l _bookmark6 1.3 研究内容 3 HYPERLINK \l _bookmark7 1.4 研究方法和技术路线 4 HYPERLINK \l _bookmark8 第二章 工程背景 7 HYPERLINK \l _bookmark9 2.1 矿床特征 7 HYPERLINK \l _bookmark10 2.1.1 地层 7 HYPERLINK \l _bookmark11 2.1.2 矿体地质特征 8 HYPERLINK \l _bookmark12 2.2 水文地质 9 HYPERLINK \l _bookmark13 2.3 采矿方法 9 HYPERLINK \l _bookmark14 第三章 材料力学参数试验与计算 13 HYPERLINK \l _bookmark15 3.1 岩体力学参数试验与计算 13 HYPERLINK \l _bookmark16 3.1.1 试验系统与装置 13 HYPERLINK \l _bookmark17 3.1.2 岩样采集与试件加工 14 HYPERLINK \l _bookmark18 3.1.3 单轴抗压强度试验 17 HYPERLINK \l _bookmark19 3.1.4 巴西劈裂拉伸试验 19 HYPERLINK \l _bookmark20 3.1.5 三轴压缩强度试验 20 HYPERLINK \l _bookmark21 3.1.
