数字矿山中三维地质建模方法与应用 总被引：1，自引：0，他引：1
三维地质建模是实现数字矿山建设的前提和核心基础,为矿业开发带来了新的机遇和动力,也面临着许多亟待解决的难题．结合矿山数据特点及数字矿山建设目标,本文提出了多源数据耦合、多种构模方法集成、多分辨率可视化与检测以及多维数据分析与应用的理论体系．针对建模流程各环节中不确定性等问题进行了分析,实现了复杂地质构模、资源储量模拟评价和采掘工程开挖等关键技术方法,随着矿山勘探、开发和复垦等进程的推进,三维地质建模历经“构建一模拟一修正”的动态更新与完善过程．实例表明,本文提出的方法能够充分利用矿山数据,在空间信息质量检测控制下,通过虚拟现实技术构建有效的三维模型,并对矿产资源进行评价预测,为矿山建设在不同阶段的各项工作提供科学依据,降低开采风险和采矿成本,提高矿山开采效率． 相似文献

《矿山地震学研究与进展专辑》索引 总被引：5，自引：0，他引：5
《矿山地震学研究与进展专辑》是由地震部门和煤炭部门专家共同编辑的一本介绍微震学在矿山应用方面的文集。该文集收录了８个国家利用地震学研究矿山震动和冲击地压（岩爆或矿山冲击）的多项成果；比较广泛地介绍了国外在矿山地震及其安全防治方面的研究进展及国内的研究动向。但因经费原因，该文集未能公开出版。为了更好地发挥这些研究成果的借鉴作用，特编辑了这本《索引》，供采矿专业与地震界的科研人员查阅。本专辑作为《矿山地震学研究与进展专辑》的文献索引，共收录了国内外论文５８篇，其中，提供了国外３８篇论文文献的题目、作者、摘要、代码、目录、图题、表题、出处、原题和译（校、审）者等１０个条目；国内文献系最近一二年和即将发表的研究成果。该索引还收录了３篇对矿山地震学的学科发展颇有见解的“序”。 相似文献

The system damping, the system frequency, the relative building response and the base rocking response peak amplitudes are studied, as those depend on the building mass and height, the flexibility of the soil, the structural damping, the type of incident waves and their angle of incidence. A linear two-dimensional model is used, which assumes the soil to be a homogeneous isotropic half-space, the foundation supporting the building to be a rigid embedded cylinder, and in which the building model is an equivalent single-degree-of-freedom oscillator. The system frequency and the system damping ratio are determined by measuring the width and the frequency of the peak in the transfer function of the oscillator relative response, using the analogy with the half-power method for a single-degree-of-freedom fixed-base oscillator. Previous similar studies are for dynamic soil-structure interaction only, and for simplified models in which the stiffness of the soil and the damping due to radiation are represented by springs and dashpots. The study in this paper differs from the previous studies in that the wave passage effects (or the kinematic interaction) are also included, and that no additional simplifications of the model are made. Results are shown for excitation by plane P- and SV-waves. 相似文献

A self-governing profiling system with a depth capability of 100 m has been developed for measuring flow velocity, temperature, salinity, and turbidity of water in the near-bottom parts of shelf seas. In the system, a moving profiler unit holding the sensors for measuring the above parameters and depth and containing a data-recording device is made to move up and down, in cycles, along a mooring line. This motion of the profiler unit is governed by a self-contained microprocessor. The system has been field-tested: examples of recorded data are presented. 相似文献

It's one thing to picture weather on other planets in the solar system, quite another to get any idea of conditions on planets orbiting other stars, but that is what researchers using the Spitzer Space Telescope have done. 相似文献
