【摘要】：煤炭资源在为国民经济发展提供动力的同时，也不可避免地带来了巨大的负面影响，如由煤炭开采引起的地表塌陷、山体滑坡和房屋损坏等。其中，最直接关乎老百姓衣食住行和生命财产安全的莫过于煤矿开采对建（构）筑物的破坏，如山西省的数千“悬空村”。在煤矿开采影响区域内的建（构）筑物下留设保护煤柱是我国煤炭行业所采取的主要保护措施。保护煤柱设计方法有传统的垂线法、垂直断面法和数字标高投影法，及应用新技术或新方法的数值模拟法、影响椭圆法等。其中，，垂线法和垂直断面法为最常用方法。从留设方法角度考虑，应用垂线法设计保护煤柱时，常会遇到受护对象边界复杂的情况，这直接使得需要采集的松散层厚度值、底板标高、地表高程和煤层倾角等基础数据的数据量庞大，垂线段错综复杂难以连接出保护煤柱边界，最终连接出的保护煤柱边界不合理等；应用垂直断面法时，因其是按照煤层走向与煤层倾向分别作剖面图以求取保护煤柱边界的图解法，难免会伴有作图复杂、精度低的弊端。从工程角度考虑，在受护对象边界形状复杂、面积比较大、松散层等厚线和部分区域地表等高线等基础资料缺乏时，常可能将工期拖延至正常情形下工期的数倍，并需要反复修改前期已完成的工作。为此，本文进行了以下研究来克服保护煤柱设计过程中可能出现的上述细节问题和困难：凸包算法基础上对建筑群进行非凸包式自动圈定，即凹多边形生成算法研究；研究受护对象边界的各种长度、角度及其组合可能产生的结果，并总结出用以指导实际项目操作的受护对象边界修正准则；研究TIN、DEM模型和空间内插方法，寻找最佳的基于离散点的等值线生成方案；通过分析等值线性质，找出实现标高、煤层倾角和煤层走向等数据自动读取的方法；研究受护对象边界形状无论是简单还是复杂，均可以实现垂线法与垂直断面法设计保护煤柱的保护边界自动绘制方案。基于以上研究，提升了保护煤柱留设的效率和精度，完善了垂线法和垂直断面法设计保护煤柱的细节处理原则，实现了设计过程的自动化。
[Abstract]:Coal resources not only provide power for national economic development, but also inevitably bring huge negative effects, such as surface collapse caused by coal mining, landslides and house damage, etc. The most direct concern for the people's food, clothing, housing, transportation and life and property is the destruction of building (construction) structures caused by coal mining. For example, thousands of "suspended villages" in Shanxi Province. It is the main protection measure adopted by the coal industry in our country to keep the protection coal pillar under the construction (construction) structure in the area affected by coal mining. The design method of protecting coal pillar has the traditional vertical line method. The vertical section method and the digital elevation projection method, and the numerical simulation method with new technology or new method are used to influence the ellipse method, among which the vertical line method and the vertical section method are the most commonly used methods. Considering from the point of view of retaining method, when using vertical line method to design coal pillar protection, the complex boundary of protected object is often encountered, which makes the thickness of loose layer and the elevation of bottom plate to be collected directly. The data of basic data such as surface elevation and coal seam inclination are so large that the perpendicular section is difficult to connect to the boundary of protecting pillar, and the boundary of protection pillar is not reasonable when the vertical section method is applied. Because it is based on the seam strike and the coal seam tendency to make the section map separately to obtain the protection coal pillar boundary diagram method, inevitably will accompany with the drawing complex, the precision is low. From the engineering angle, in the protected object boundary shape is complex, the area is relatively large, When the basic data such as the loose layer isoparic line and the surface contour of some areas are lacking, it is often possible to delay the time limit to several times of the normal time limit, and to modify the work done in the early stage repeatedly. In this paper, the following research is carried out to overcome the above detailed problems and difficulties that may occur in the process of coal pillar protection design: the concave polygon generation algorithm is studied on the basis of the convex hull algorithm for the construction group of non-convex hull automatic delineation; The possible results of various lengths, angles and combinations of the boundary of the protected object are studied, and the boundary correction criteria of the protected object used to guide the operation of the actual project are summarized, and the TINDEM model and the spatial interpolation method are studied. To find the best isoline generation scheme based on discrete points; to find out the method of automatically reading elevation, seam dip angle and coal seam strike by analyzing the properties of isoline; to study the boundary shape of protected object, whether simple or complex, Both vertical section method and vertical section method can be used to design the automatic drawing scheme of protecting coal pillar. Based on the above research, the efficiency and precision of protecting pillar setting are improved. The principle of detail processing for the design of coal pillar protection by vertical section method and perpendicular method is improved, and the automation of the design process is realized.
