【摘要】 我国是全世界少数几个利用一次性煤炭为主的国家之一,也是煤与瓦斯突出灾害最严重的国家之一。我国大部分产煤的省份基本都发生过煤与瓦斯突出现象。随着社会化进程的不断向前,基础设施建设投入的不断加大,我国对煤矿需求量也随之不断的增加。在市场需求压力下,煤矿采掘深度不断的加大,我国煤与瓦斯突出的危险性也日益的严重。通过生产实践证明,煤层瓦斯预抽措施在煤与瓦斯突出防治工作中可起到治标治本的作用。因此,煤层瓦斯抽采效果达标的瓦斯治理战略使得许多突出矿井有效的遏制了煤与瓦斯突出事故的发生。煤层瓦斯预抽措施在执行过程中仍存在着不少的问题,比如钻孔施工深度、钻孔控制范围、终孔间距等任何一项达不到设计要求,都会直接影响到瓦斯抽采效果。部分矿井由于“抽、掘、采”不平衡,出现瓦斯抽放与煤矿采掘发生冲突时,很多时候都是弃抽保产,整个瓦斯抽采没有得到时间的保障,同样没有达到防突的效果。通过分析得知,煤层瓦斯抽采措施实施过程中存在的问题大部分都与空间分析管理技术紧密联系在一起。信息化技术发展至今,地理信息系统(Geographic Information System, GIS)的空间信息表达和管理技术的优越性越来越得到社会的认可。煤矿生产将GIS技术引入之后已经得到了一些喜人成果,例如数字矿山和煤矿综合预警技术都充分利用了GIS技术的空间信息管理的优越性。因此,本文针对煤矿瓦斯抽采措施所存在的问题和目前GIS在煤矿安全管理中的应用,提出了基于GIS的煤矿瓦斯抽采达标系统的设计与实现。本文是在整个煤矿瓦斯抽采工作的理论方法及抽采达标评价理论模型的研究基础之上,结合煤矿瓦斯抽采工作的主要业务需求,设计的一个基于GIS的煤矿瓦斯抽采达标系统框架方案,并从理论模型、系统结构、功能实现和案例分析等方面对整个过程做了详细的介绍；同时,对于该系统实现所涉及到的部分重要功能的相关技术进行了探讨,并利用Visual Studio C#.Net语言,基于Mapobjects开发包和SQL Server数据库完成了系统的设计与实现；本文利用通过Visual Studio C#进行了煤矿瓦斯抽采达标工作中相关功能开发。主要包含了瓦斯抽采系统监测监控、抽采日常管理、抽采效果评价及预测三个方面相关功能的实现。针对于目前抽采达标工作所需要的GIS空间信息技术,利用Mapobjects开发包完成了基础GIS平台的开发,其中包含了基本图形数据的导入、新建、修改、保存、成图等基本功能。并在Mapobjects已有图形功能基础上完成了相关功能的完善,其中相对比较重要的参数等值线生成就是利用稀疏点数据等值线生成方法进行自行开发补充。对于系统中点数据符号化问题利用图层预先编辑后调用进行完善和处理。最后利用通信接口将数据管理和瓦斯抽采达标预测预判、抽采效果评价、施工情况管理等图形要素相结合。整个系统的设计与开发都相对比较有其独有性。最后,利用该系统对煤与瓦斯突出防治工作的管理应用做了相应的案例分析。通过案例的应用分析表明,本文所设计的基于GIS的煤矿瓦斯抽采达标系统不仅仅是简单的利用计算机辅助生产,而且促进了GIS技术与煤矿安全生产领域的进一步融合。该系统利用GIS对空间信息的表达和管理技术对瓦斯抽采工作效果表达做了更好的展现,提高了整个瓦斯抽采达标工作的空间化管理,扩展了现阶段瓦斯抽采达标工作的技术手段和表现力度,对于整个GIS在该领域的下一步研究工作具有一定的应用价值。更多还原

【Abstract】 China is the world’s one of the few one-time coal used country, and our coal and gas outburst accident is the most serious disaster in coal mine safety. Most of the country’s coal-producing provinces are basically had coal and gas outburst accident. With the continuous advance of our socialization process, the infrastructure continues to increase meanwhile the amount of demand for the coal mine is also constantly increasing. With the continuous increase of the depth of the coal mining of coal, the gas outburst risk is also increasingly serious. Through the production practice has proved that, the coal seam gas predrainaging measures can play a root role in the outburst prevention work. Coal seam gas drainage effect reach the standards is many outburst mine gas control strategy to effectively curb the outburst accident occurred.Coal seam gas pre-pumping measures still exist many problems in the implementation process, such as the depth of the borehole construction, drilling control the scope, the final hole spacing, if one of them less than the design requirements, will directly affect the gas drainage. Part of the mine gas drainage, digging, mining imbalance, and the gas drainage and coal mining conflict, often are abandoned gas drainage persist production, the entire gas drainage not have the time protection, did not reach the effect of outburst prevention.Analysis of coal seam gas predrainaging measures problems existing in the process most of them are closely linked spatial analysis techniques. With the development of information technology, the superiority of the spatial information expression and management technology on Geographic Information System are more and more recognized by society. Coal production on the introduction of GIS technology has been got some gratifying results; digital mine and coal mines warning technology have full use of GIS technology of spatial information management superiority. Therefore, for the coal mine gas drainage measures exist problems and the GIS apply in the coal mine safety management, designing and implementing the GIS-based coal mine gas drainage reach standards system.This paper is based on study of the theory of the entire coal mine gas drainage and the evaluation theoretical model of the gas drainage reach standard, and combination of coal mine gas drainage work business needs, design the framework of a GIS-based coal mine gas drainage reach standards system, and from the theoretical model, system architecture, functional implementation and case analysis, made a detailed introduction to the entire process. Meanwhile, the technologies involved to some important features of the system are discussed, using the Visual Studio C#. Net language design and implementation of the system is based on mapobjects development kit and SQL Server database. Finally, using this system make the case analysis of coal and gas outburst prevention and control of the management.Using Visual Studio C#to develop the gas drainage reach standard system function. Consist mainly of gas drainage system monitoring and control, day-to-day management of drainage, drainage effect evaluation and prediction of the function of the realization of the three aspects. For Currently gas drainage system work needed GIS spatial information technology using MapObjects development kit to complete the basic GIS platform develop, containing basic graphical data import, new create, modify, save, and map export and other basic functions. The other related functions is improve on the basis of the Mapobjects, relatively important parameter contour generation is used sparse point data contour generation method to self-developed supplement. Using Layer pre-edit and call to perfect and processing for the system point data symbolization. Finally, using the communication interface to combine the data management and graphical management, like gas drainage reach standards to predict anticipation, drainage effect evaluation, construction information management. The system’s design and development is relatively unique. Finally, the system use coal and gas outburst prevention and control work management to do the case studies.Through the application of analysis of the case show that the design of GIS-based coal mine gas drainage reach standard system is not only just a simple use of computer-aided production, also promote the further integration of GIS technology and coal mine production safety. The system uses GIS spatial information expression and management techniques work the effect of gas drainage express better performance, improve the space information management of the entire gas drainage reach standard, expanded this stage gas drainage reach standard technology’s means and expressive,is good for the further research work in this field for the entire GIS.更多还原
