本规范规定了煤炭资源及其相关地质工作中地面电法勘探的设计编制、野外施工、质量评价、资料处理与解释、报告编制和审查验收等工作的基本要求和技术规则。
本规范适用于煤炭资源地质勘探及与煤炭资源相关的各种比例尺地质填图、矿区水文地质工程地质勘查、供水水文地质勘探中的地面电法勘探工作。同时也可供煤炭各类工程地质、环境地质、灾害地质等勘探中的地面电法勘探工作参考.

Introduction

Standard Evolution and Technological Development

This specification replaces the 1980 edition of "Coalfield Electrical Exploration Code", integrates modern exploration methods such as digital electrical technology, and adds 5 branch technologies such as transient electromagnetic method, which improves the exploration accuracy by more than 40%.

Technical Specifications of Core Methods

Method	Key Parameters	Accuracy Requirements	Applicable Scenarios
DC Resistivity Sounding Method	AB/2 Interpolar Ratio≤1.5 MN≤AB/3	Single Interpolar Ratio Error≤10%	Coal Seam Depth Detection
Induced Polarization Method	MN/AB=1/3 ΔV₂≥10ΔV_n	η_sError≤7%	Aquifer identification

Quality control system

Three-level quality inspection mechanism

1. On-site self-inspection: 3% repeated measurements at daily observation points, with a range ≤5%

2. System detection: detection points are evenly distributed throughout the area, and the A-level rate ≥60% is qualified

3. Acceptance rating: excellent (A-level rate ≥80%), good, and qualified

Typical application case

A mining area in Shanxi Province uses Electromagnetic frequency sounding method, through the setting of the receiving and transmitting distance of r≥3H (target layer depth), successfully delineated the Ordovician limestone karst development zone, the exploration depth exceeded 800 meters, and the anomaly verification coincidence rate reached 85%.
