Introduction

According to the "Water Law of the People's Republic of China," the relevant provisions of groundwater resources in order to promote the rational development and effective protection, unified underground Water over-mining area division, evaluation and monitoring of the technical requirements, strengthen scientific management of over-exploitation of groundwater, especially formulated this standard. On May 12,.2003, the Ministry of Water Resources of the People's Republic of China promulgated the Guidelines for the Evaluation of Groundwater Overdraft Areas (SL286-2003) August 1,.2003 implementation. According to the "groundwater over-mining area evaluation guidelines" (SL286-2003) since the implementation of the accumulated experience and discovery Issue, combined with the current most stringent water resources management system requirements, formulate and promulgate this standard. Groundwater overdraft area evaluation guidelines

1 Scope

This standard specifies the groundwater over-mining area classification, grading requirements and standards, over-mining zone naming and coding rules, over-mining area and step-by-step Requirements, evaluation content and requirements of overdrawn area and dynamic monitoring, investigation and data reorganization requirements of overdrawn area. This standard is applicable to the division, evaluation and over-exploitation of groundwater over ground dynamic monitoring, investigation and data reorganization and other work.
