【摘要】：矿山开采过程中伴随的动力灾害具有随机性、突发性和破坏形式的多样性,单凭一种预测方法难以准确预测预报。工程实践表明,要实现动力灾害的预测,必须以工程地质、地应力场测量分析、矿岩力学特性为基础,结合数值模拟方法和多种监测手段,综合分析各种信息来达到灾害预测的目的。基于灾害危险性分析方法,本文提出了灾害危险性综合分析技术,以软件系统为载体,开发出一套“强矿压灾害危险性多维信息综合分析系统”专用软件。以ArcGIS Engine空间数据库为基础,构建了涵盖矿山地测信息、数值计算信息以及监测信息的多种信息综合存储体系,为实现灾害危险性综合分析提供了数据基础。论文的主要工作有： (1)从常见的三维实体模型类别中选择不规则三角网来表达矿山地质实体,以MultiPatch数据类型表达三维实体模型。研究了Surpac三维实体模型数据与ArcGIS中MultiPatch数据结构的关系,实现了从Surpac数据格式到MultiPatch数据格式的转换,以达到由Surpac构建的三维矿体模型在本系统中可视化的目的。 (2)实现了数值计算信息的存储,为灾害危险性分析提供数据基础；对数值计算信息进行了剖切处理,通过剖切结果实现了矿区范围内任意位置在垂直于x、y、z三个方向剖面的最大主应力、最小主应力以及剪应力等分布情况的快速查询以及顶板、底板和煤层的最大主应力、最小主应力以及剪应力等分布情况的快速查询和分析。 (3)实现了微震监测数据的存储及查询。根据微震事件信息,实现了对冲击事件所处位置的地质环境、应力环境以及能量分布情况的分析,以此为依据,为灾源的识别提供分析依据。 (4)基于地质信息、数值计算信息和监测信息数据,综合考虑岩性材料信息、应力环境信息,实现了矿区灾害危险性综合分析,并在系统中以云图形式直观展示了矿区灾害危险性区域的等级划分。
[Abstract]:With the dynamic disasters in mining process is random, the diversity of the sudden and destructive forms, with a prediction method is difficult to accurately forecast. The engineering practice shows that the prediction to achieve dynamic disaster, must be based on the engineering geological analysis, field in-situ stress measurement, rock mechanics characteristics as the basis, combined with a variety of methods and monitoring method of numerical simulation, a comprehensive analysis of all information to achieve the purpose of disaster forecasting. Based on hazard analysis method, this paper puts forward the comprehensive hazard analysis technology, the software system as the carrier, developed a set of "strong mine pressure hazard comprehensive analysis of multi-dimensional information system software.
Based on the ArcGIS Engine spatial database, a comprehensive information storage system covering all the information of mine geological survey, numerical calculation and monitoring information is built, which provides data basis for comprehensive analysis of disaster risk.
(1) select the triangulated irregular network category from the 3D model to express the common mine geological entity, the expression of 3D model based on MultiPatch data types. To study the relationship between the data structure of MultiPatch data and ArcGIS Surpac three-dimensional entity model, to achieve the conversion from Surpac data format to MultiPatch data format, three-dimensional model of ore body reached by the construction of Surpac visualization in the system.
(2) the numerical information storage, provide the data base for hazard analysis; the numerical information of the cutting process, cutting through the results achieved at any position within the mining area in the direction perpendicular to the X, y, Z three directions of the maximum principal stress profile, the minor principal stress and the shear stress distribution of the fast query and roof, coal seam floor and the maximum principal stress, minimum principal stress and fast query and analysis of shear stress distribution.
(3) to realize the storage and query of microseismic monitoring data. According to microseismic event information, the geological environment on the impact event, stress analysis of environment and energy distribution, on this basis, to provide source identification and analysis basis.
(4) based on geological information, numerical calculation information and monitoring information data, taking into account lithology material information and stress environment information, we realized the comprehensive analysis of mine disaster risk. In the system, we used cloud map form to show the level classification of mine disaster risk area in an intuitive way.
