| 1 | Large-scale deformation monitoring in mining area by D-InSAR and 3D laser scanning technology integration显示文摘Large-scale deformation can not be detected by traditional D-InSAR technique because of the limit of its detectable deformation gradient,we propose a method that combines SAR data with point cloud data obtained by 3D laser scanning to improve the gradient of deformation detection.The proposed method takes advantage of high-density of 3D laser scanning point cloud data and its high precision of point positioning after 3D modeling.The specifc process can be described as follows:frst,large-scale deformation points in the interferogram are masked out based on interferometric coherence;second,the interferogram with holes is unwrapped to obtain a deformation map with holes,and last,the holes in the deformation map are flled with point cloud data using inverse distance weighting algorithm,which will achieve seamless connection of monitoring region.We took the embankment dam above working face of a certain mining area in Shandong province as an example to study large-scale deformation in mining area using the proposed method.The results show that the maximum absolute error is 64 mm,relative error of maximum subsidence value is 4.95%,and they are consistent with leveling data of ground observation stations,which confrms the feasibility of this method.The method we presented provides new ways and means for achieving large-scale deformation monitoring by D-InSAR in mining area. | Chen Bingqian Deng Kazhong Fan Hongdong Hao Ming | 2013 | International Journal of Mining Science and Technology2013，23，4： | 12 |
| 2 | 多种地质采矿因素复合影响下开采沉陷规律分析显示文摘为了研究山区倾斜煤层重复开采条件下的地表沉陷规律及其影响因素,以镇城底矿南六采区下组煤首采工作面为例,通过设立地表移动观测站,得到观测站所在的28620工作面的地表移动变形主要参数,并分析沉陷规律与机理。观测结果分析表明,在工作面两侧地形条件、老采空区条件类似的情况下,倾向主断面上沉陷曲线形态呈现不对称性分布,其原因主要是两侧微观地形差异、地表覆被差异和老采空区形成时间差异的联合影响造成的,地质、采矿多因素复合影响下的沉陷规律不能简单套用单因素影响下的规律。研究结果可为当地矿山开采和地物保护提供指导,为其他复合因素影响下的开采沉陷研究提供参考。 | 康新亮 蔡音飞 | 2021 | 矿业安全与环保2021，48，4： | 9 |

| 4 | 基于化学注浆预加固的破碎矿体采场结构优化数值模拟显示文摘汤丹铜矿4号矿体厚大软弱破碎,围岩松散、炮孔成孔率低;优选MP 364矿用树脂进行化学注浆预加固,并在3采2分段进行现场化学注浆试验,确定化学浆液扩散方式、注浆压力及扩散半径等参数,建成注浆工艺系统。通过FLAC 3D及ANSYS等软件建模,并对地表岩移、顶板位移、采场支撑体系塑性区以及矿柱最大主应力进行数值模拟分析。研究结果表明:按照推荐注浆材料配比及工艺施工,岩体强度及完整性得到较大提高,炮孔成孔率提高22%;化学注浆后,由于岩体强度及矿体完整性得到提高,拟通过增大矿房暴露面积以提高矿石回收率。注浆后,在保证安全且保持矿柱尺寸不变的情况下,矿房暴露面积提高约50 m2,则矿石回收率可以提高约10%以上,提高了矿山经济效益。 | 韩斌 于少峰 吴爱祥 高永祥 程海勇 | 2015 | 中南大学学报(自然科学版)2015，46，10： | 6 |

| 6 | Heat transfer and temperature evolution in underground mininginduced overburden fracture and ground fissures: Optimal time window of UAV infrared monitoring显示文摘Heat transfer and temperature evolution in overburden fracture and ground fissures are one of the essential topics for the identification of ground fissures via unmanned aerial vehicle(UAV) infrared imager. In this study, discrete element software UDEC was employed to investigate the overburden fracture field under different mining conditions. Multiphysics software COMSOL were employed to investigate heat transfer and temperature evolution of overburden fracture and ground fissures under the influence of mining condition, fissure depth, fissure width, and month alternation. The UAV infrared field measurements also provided a calibration for numerical simulation. The results showed that for ground fissures connected to underground goaf(Fissure Ⅰ), the temperature difference increased with larger mining height and shallow buried depth. In addition, Fissure Ⅰ located in the boundary of the goaf have a greater temperature difference and is easier to be identified than fissures located above the mining goaf. For ground fissures having no connection to underground goaf(Fissure Ⅱ), the heat transfer is affected by the internal resistance of the overlying strata fracture when the depth of Fissure Ⅱ is greater than10 m, the temperature of Fissure Ⅱ gradually equals to the ground temperature as the fissures’ depth increases, and the fissures are difficult to be identified. The identification effect is most obvious for fissures larger than 16 cm under the same depth. In spring and summer, UAV infrared identification of mining fissures should be carried out during nighttime. This study provides the basis for the optimal time and season for the UAV infrared identification of different types of mining ground fissures. | Yixin Zhao Kangning Zhang Bo Sun Chunwei Ling Jihong Guo | 2024 | International Journal of Mining Science and Technology2024，34，1： | 0 |
