【摘要】：在我國(guó)，煤炭資源的開采對(duì)促進(jìn)整個(gè)國(guó)民經(jīng)濟(jì)發(fā)展具有重要的推動(dòng)意義。由于我國(guó)對(duì)煤炭的需求量較大，建筑物下、鐵路下和水體下的煤炭開采強(qiáng)度和開采范圍在不斷地?cái)U(kuò)大，造成了較大規(guī)模和范圍的地表移動(dòng)與變形，導(dǎo)致地表建（構(gòu)）筑物因地基承受力下降而受到損壞。這一現(xiàn)象不僅嚴(yán)重影響了處于采空區(qū)上方的道路、住宅小區(qū)及工礦企業(yè)等的正常使用及運(yùn)營(yíng)，而且威脅到了在礦區(qū)中生產(chǎn)生活的人民的安全。因此，為了最大限度地減小煤炭開采對(duì)礦區(qū)造成的地面沉陷災(zāi)害影響，研究、預(yù)測(cè)礦區(qū)開采沉陷對(duì)地面建（構(gòu)）筑物的影響程度是十分必要和迫切的。 本文針對(duì)開采對(duì)地面村莊房屋建筑的損害影響問(wèn)題，在求得礦區(qū)開采沉陷地表移動(dòng)變形預(yù)計(jì)結(jié)果的基礎(chǔ)上，以Visual Basic語(yǔ)言為開發(fā)工具，結(jié)合圖形處理工具AutoCAD二次開發(fā)的基本思想以及Access數(shù)據(jù)庫(kù)管理系統(tǒng)，，設(shè)計(jì)開發(fā)得到建筑物采動(dòng)損害評(píng)估可視化系統(tǒng)，以預(yù)測(cè)開采對(duì)地面村莊建筑的損害范圍和損害程度。主要完成了以下工作： （1）分析研究概率積分法原理以及與實(shí)例礦區(qū)相同地質(zhì)條件下煤炭開采造成的地表移動(dòng)變形規(guī)律，并以此為基礎(chǔ)，應(yīng)用山區(qū)煤礦開采地表移動(dòng)變形預(yù)計(jì)軟件MMSPS對(duì)礦區(qū)開采沉陷地表移動(dòng)變形規(guī)律進(jìn)行預(yù)計(jì)。 （2）結(jié)合AutoCAD強(qiáng)大的編輯功能、圖形功能和高度的開放性，著重研究了基于AutoCAD二次開發(fā)技術(shù)構(gòu)建移動(dòng)變形等值線以及損害等級(jí)分布可視化的方法。 （3）在實(shí)現(xiàn)開采損害等級(jí)評(píng)估可視化的基礎(chǔ)上，通過(guò)系統(tǒng)得到開采對(duì)地面建筑物損害的評(píng)價(jià)結(jié)果，應(yīng)用系統(tǒng)的信息統(tǒng)計(jì)分析和查詢功能，對(duì)地面建筑損害評(píng)價(jià)信息進(jìn)行了細(xì)致的匯總，以及自動(dòng)生成諸如房屋破壞面積和沉陷面積等各種信息的專題地圖；實(shí)現(xiàn)了部分屬性查詢結(jié)果與圖形中對(duì)應(yīng)特征部分的同步高亮顯示，使得查詢結(jié)果一目了然；另外，系統(tǒng)可隨時(shí)選擇并輸出用戶需要的圖形結(jié)果和查詢統(tǒng)計(jì)結(jié)果，體現(xiàn)了系統(tǒng)信息保存的實(shí)時(shí)性。 （4）選取某城尹家煤礦為研究對(duì)象，針對(duì)該礦區(qū)尹家村東北部采空區(qū)的具體地質(zhì)采礦條件，進(jìn)行了建筑物采動(dòng)損害評(píng)估可視化系統(tǒng)的工程實(shí)際應(yīng)用，文中詳細(xì)介紹了整個(gè)預(yù)計(jì)和可視化評(píng)價(jià)的過(guò)程，得到的開采損害等級(jí)評(píng)價(jià)結(jié)果鮮明、突出，對(duì)礦區(qū)的下一步開采工作具有一定的指導(dǎo)意義。 本文開發(fā)的建筑物采動(dòng)損害評(píng)估可視化系統(tǒng)易于操作，得到的損害評(píng)估結(jié)果簡(jiǎn)潔明了，直擊重點(diǎn)，不僅可以實(shí)現(xiàn)系統(tǒng)開發(fā)的各種圖形繪制、顯示、查詢、統(tǒng)計(jì)等功能，還保留了AutoCAD自身強(qiáng)大的圖形操作功能，對(duì)礦區(qū)的開采沉陷損害預(yù)測(cè)及可視化的實(shí)現(xiàn)具有重要的現(xiàn)實(shí)意義。
[Abstract]:In our country, the exploitation of coal resources is of great significance to promote the development of the whole national economy. Due to the large demand for coal in China, the intensity and scope of coal mining under buildings, railways and water bodies are constantly expanding, resulting in the surface movement and deformation on a large scale and scope. As a result, the surface building is damaged by the decrease of the bearing capacity of the foundation. This phenomenon not only seriously affects the normal use and operation of roads, residential areas and industrial and mining enterprises above the goaf, but also threatens the safety of the people who produce and live in the mining areas. Therefore, in order to minimize the impact of coal mining on surface subsidence disasters in mining areas, It is necessary and urgent to predict the influence of mining subsidence on ground building. On the basis of obtaining the predicted results of ground movement and deformation of mining subsidence in mining area, taking Visual basic language as development tool, combining with the basic idea of AutoCAD secondary development and Access database management system, The visual system of building mining damage assessment is designed and developed to predict the damage scope and damage degree of mining to the ground village building. The main work is as follows: 1) the principle of probabilistic integration method and the law of ground surface movement and deformation caused by coal mining under the same geological conditions are analyzed and studied. This paper applies the software MMSPS to predict the law of surface movement and deformation in mining subsidence of mining area in mountainous area. Combined with the powerful editing function of AutoCAD, the graphic function and the high openness of AutoCAD, the software MMSPS is used to predict the law of surface movement and deformation of mining subsidence in mining area. Based on the secondary development technology of AutoCAD, the method of constructing the moving deformation isoline and the visualization of damage grade distribution is studied. The evaluation results of ground building damage caused by mining are obtained by the system. The information of ground building damage evaluation is summarized carefully by using the system information statistic analysis and query function. And automatic generation of various information such as building damage area and subsidence area thematic map; part of the attribute query results and the corresponding features in the graphics of the synchronized highlight, so that the query results at a glance; in addition, The system can select and output the graph result and the query statistic result of the user at any time, which reflects the real time of the information preservation of the system. 4) A certain city Yinja coal mine is selected as the research object. In view of the specific geological and mining conditions of the goaf in the northeast of Yinjiacun in this mining area, the practical application of the visual system for building mining damage assessment is carried out, and the whole process of prediction and visual evaluation is introduced in detail in this paper. The result of evaluation of mining damage grade is clear and outstanding, which has certain guiding significance for the next mining work in mining area. The visual system of building mining damage assessment developed in this paper is easy to operate. The result of damage assessment is simple and clear, and it can not only realize the functions of drawing, displaying, querying, statistics and so on, but also retain the powerful graphic operation function of AutoCAD itself. It has important practical significance for mining subsidence damage prediction and visualization.
