1.1本规程涵盖了确定地表煤炭开采许可证边界的准确位置和数据描述的最低要素。 1.1.1本规程涉及与1977年《露天采矿控制和复垦法案》（SMCRA）相关的煤矿地理空间边界数据。该地理空间数据应从根据SMCRA授权监管露天煤矿作业（SCMO）的每个州或联邦或两者的煤矿监管局（RA）获得。每个RA应为煤矿地理空间数据的权威数据源（ADS）。 1.1.2在本实践中，地表煤炭开采许可证边界表示煤炭移除和回收以及相关支持活动已经发生、正在发生或由RA在定义的SCMO内规划和授权的区域。 1.2本惯例仅限于SMCRA通过后的露天煤矿作业。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。 本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 1.4本规程提供了一套用于执行一个或多个特定操作的说明。本文件不能取代教育或经验，应与专业判断一起使用。并非本惯例的所有方面都适用于所有情况。本ASTM标准不代表或取代必须根据其判断给定专业服务的充分性的谨慎标准，也不应在不考虑项目的情况下应用本文件 ’ 它有许多独特的方面。文字 “ 标准 ” 在本文件标题中，仅表示该文件已通过ASTM共识程序获得批准。 ====意义和用途====== 本规程涉及与SMCRA和30 CFR第700部分等相关的煤矿地理空间边界数据。 这一做法对煤矿界具有重要意义，因为它提供了与美国地表煤炭开采边界有关的统一地理空间数据。地表煤炭开采边界是将由RA开发使用的第一个煤炭开采地理空间数据标准。在其专属管辖区内，每个RA是其创建并用于实施SMCRA的煤矿空间数据的权威数据源（ADS）。这些标准将有助于确保内部商业实践中使用的煤炭开采地理空间数据的一致性，在煤炭开采社区内的商业伙伴之间交换，并由每个ADS在未来创建描述美国地表煤炭开采的国家数据集的努力中贡献。 笔记 1-目前，并非所有RAs都建立了煤矿地理空间数据集。在拥有煤矿地理空间数据集的RAs中，每个RAs使用自己的坐标系、命名约定和术语，以不同的方法组织数据。 通过建立国家数据标准，RAs将为煤矿地理空间数据的创建和管理提供统一的指导。实际上，这种做法创造了一种更简单、更有效的方式，在受影响方之间利用和共享地表煤矿边界地理空间数据。 地表煤炭开采地理空间数据应从SCMO的州和联邦监管机构获得。煤炭开采社区包括所有直接和间接受煤炭开采活动影响的实体，包括行业、环境团体、公众和美国各级政府。使用该标准将有助于创建一致的地图，并提高对美国各地SCMO站点的了解。本标准促进创建组织良好且易于访问的地表煤炭开采数据，并将促进州和联邦办公室、公众、行业和环境团体之间的更好沟通。 除了定义许可证边界外，随着时间的推移，使用该标准将允许识别边界随雷区变化而发生的变化。 在少数产煤州中，地表煤炭开采边界的某些属性将没有价值。某些州的地表煤炭开采边界国家数据集似乎不完整。在某些情况下，可能没有为这些州收集地表煤炭开采地理空间数据。在其他情况下，它不适用。 本标准符合美国联邦地理数据委员会（FGDC）颁布的数据内容标准定义。识别地理特征和描述数据模型的术语和定义已采用FGDC空间数据传输标准（ANSI INCITS 320-1998（R2003））和FGDC框架数据内容标准（FGDC项目1574-D）信息技术 地理信息框架数据内容标准，第5部分: 政府单位和其他地理区域边界。 虽然本标准专门为露天煤矿行业编写，但其一般用途和内容适用于其他露天采矿作业。

1.1 This practice covers the minimum elements for the accurate location and description of data for defining a surface coal mining permit boundary. 1.1.1 This practice addresses coal mining geospatial boundary data relative to the Surface Mining Control and Reclamation Act of 1977 (SMCRA). This geospatial data shall be obtained from each state or federal, or both, coal mining regulatory authority (RA) authorized under SMCRA to regulate surface coal mining operations (SCMO). Each RA shall be the authoritative data source (ADS) for coal mining geospatial data. 1.1.2 As used in this practice, a surface coal mining permit boundary represents an area where coal removal and reclamation and related supporting activities have occurred, is occurring, or is planned and authorized by the RA within a defined SCMO. 1.2 This practice is limited to surface coal mining operations after passage of SMCRA. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1.4 This practice offers a set of instructions for performing one or more specific operations. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project ’ s many unique aspects. The word “ Standard ” in the title of this document means only that the document has been approved through the ASTM consensus process. ====== Significance And Use ====== This practice addresses coal mining geospatial boundary data relative to the SMCRA and 30 CFR Part 700 et seq. This practice is significant to the coal mining community because it provides uniformity of geospatial data pertaining to surface coal mining boundaries throughout the United States. The surface coal mining boundary is the first of the coal mining geospatial data standards to be developed for use by a RA. Within its area of exclusive jurisdiction, each RA is the authoritative data source (ADS) for coal mining spatial data that it creates and uses to implement SMCRA. These standards will help ensure uniformity of coal mining geospatial data used in internal business practices, exchanged among business partners within the coal mining community, and contributed by each ADS in future efforts to create national datasets describing surface coal mining in the United States. Note 1—Currently, not all RAs have established datasets for coal mining geospatial data. Of those RAs that have coal mining geospatial datasets, each organizes their data in a different method, using their own coordinate system, and their own naming conventions and terminology. By establishing national data standards, RAs will have uniform guidance for the creation and management of coal mining geospatial data. In effect, this practice creates an easier and more efficient way to utilize and share surface coal mining boundary geospatial data among affected parties. Surface coal mining geospatial data shall be obtained from State and Federal regulatory authorities for SCMO. The coal mining community encompasses all entities directly and indirectly affected by coal mining activities, including industry, environmental groups, the general public, and the government at all levels within the United States. Use of this standard will help create consistent maps and increase understanding of SCMO sites throughout the United States. This standard promotes the creation of well organized and easily accessible surface coal mining data, and it will facilitate better communication between state and federal offices, the public, industry and environmental groups. In addition to defining a permit boundary, use of this standard over time will allow identification of changes in the boundary as the mined area changes. Among a few coal-producing states, some attributes of the surface coal mining boundaries will not have values. A national dataset of surface coal mining boundaries will appear to be incomplete for certain states. In some situations, surface coal mining geospatial data may not have been collected for those states. In others, it is not applicable. This standard conforms to the definition of a Data Content Standard as promulgated by the U.S. Federal Geographic Data Committee (FGDC). Terminology and definitions for identifying geographical features and describing the data model has been adopted from the FGDC Spatial Data Transfer Standard (ANSI INCITS 320-1998 (R2003)) and the FGDC Framework Data Content Standard (FGDC Project 1574-D) Information Technology Geographic Information Framework Data Content Standard, Part 5: Governmental Unit and Other Geographic Area Boundaries. Although this standard is written specifically for the surface coal mining industry, its general purpose and content are applicable to other surface mining operations.
