Map Viewing Service (WMS) of the dataset: List of digital mine risk prevention plans in the Aveyron department

The Natural Risk Prevention Plans (PPRN) were established by the Act of 2 February 1995 on strengthening the protection of the environment. The system was supplemented by the plans for the prevention of mining risks introduced by Law No 99-245 of 30 March 1999 on liability for damage resulting from mining and the prevention of mining risks after the end of the operation, codified in the new Mining Code (Article L174-5). They are the key instrument of the State in the field of risk prevention. Their objective is to monitor development in areas exposed to a major risk. The PPRs are approved by the prefects and generally carried out by the departmental directorates of the territories (DDT). These plans regulate land use or land use through building prohibitions or requirements on existing or future buildings (constructive provisions, vulnerability reduction work, restrictions on agricultural use or practices, etc.). These plans may be under development (prescribed), implemented in advance or approved. The RPP file contains a presentation note, a regulatory zoning plan and a regulation. Other graphic documents that are useful for understanding the approach (e.g. hazards, issues, etc.) can be attached. Each PPR is identified by a polygon that corresponds to the set of affected municipalities within the scope of the prescription when it is in the prescribed state; and the envelope of restricted areas when it is in the approved state. This geographical table makes it possible to map existing PPRMs on the department. Each PPR document existing in this spatial dataset is linked with its GASPAR code “ddd[PREF|DDT|DDTM|DREAL]aaaannnn” (AAAA and NNNN correspond to the reference year and serial number of the associated PPR procedure in GASPAR): 1. its administrative procedure for drawing up (or revising) managed in the GASPAR application, on the one hand, 2. its set of constituent geographic data described in the metadata sheet N_PPRM_AAAANNNN, on the other hand.自然风险预防计划（Natural Risk Prevention Plans, PPRN）由1995年2月2日《加强环境保护法案》确立。1999年3月30日第99-245号法律引入的采矿风险防控计划对该体系进行了补充——该法律对采矿活动引发的损害赔偿责任以及运营终止后的采矿风险防控作出规定，并被纳入新《矿业法典》第L174-5条。 此类计划是国家在风险防控领域的核心工具，其目标是对存在重大风险的区域的开发活动进行监测。自然风险预防计划（PPRs）由省长批准，通常由领土事务省局（Direction Départementale des Territoires, DDT）牵头实施。此类计划通过对既有或未来建筑设定建筑禁令或相关要求（包括建设规范、风险脆弱性消减工程、农业使用限制或农业活动限制等），对土地利用或土地开发行为进行管控。 此类计划可处于编制中（即已下达编制指令）、提前实施或已获批状态。RPP文件包含说明性说明、合规分区规划以及管控规则。其他有助于理解该方案的图文资料（如风险隐患、相关问题等）可作为附件附后。每份PPR均通过多边形进行标识：当计划处于编制指令状态时，该多边形对应指令范围内受影响的所有市镇；当计划处于获批状态时，该多边形对应受限区域的范围边界。该地理数据表可用于在省内绘制现有PPRM的空间分布图。 此空间数据集中的每份PPR文档均关联其GASPAR代码“ddd[PREF|DDT|DDTM|DREAL]aaaannnn”（其中AAAA与NNNN分别对应GASPAR系统中相关PPR流程的参考年份与序列号）：一方面是在GASPAR系统中管理的编制（或修订）行政流程，另一方面是元数据表N_PPRM_AAAANNNN中描述的组成地理数据集。
