前言
本标准是为了适应煤炭资源地质勘查工作的需要,在原煤炭工业部1980年颁发的有关规程基础上,总结20多年执行过程的实践经验,结合当前我国经济发展和技术进步而制定的。
本标准自生效之日起,同时替代原煤炭工业部(80)煤地字第638号文件颁发的《煤炭资源地质勘探抽水试验规程》、《煤炭资源地质勘探地表水、地下水长期观测及水样采取规程》、《煤炭资源地质勘探钻孔简易水文地质观测规程》和《煤田水文地质测绘规程》。
本标准的附录A、B、C为规范性附录,附录D、E、F、G、H、I、J、K、L为资料性附录。
本标准由中国煤炭工业协会提出。
本标准由全国煤炭标准化技术委员会归口。
本标准起草单位:
中国煤炭地质总局、中国煤炭地质总局第一勘探局、中国煤炭地质总局水文地质局。
本标准起草人:
孙玉臣、程爱国、王佟、傅耀军、郑柏平、华解明、袁同星、龚汉宏、牛志刚、段建华、白喜庆、李洪。
本标准为首次发布。
煤矿床水文地质、工程地质及环境地质勘查评价标准
1范围
本标准规定了煤炭资源地质勘查水文地质、工程地质及环境地质工作的基本准则,侧重于勘查技术要求、工作方法。
本标准适用于煤炭资源地质勘查各阶段的设计编制、勘查施工、地质研究、地质报告编制和评审、资源/储量评估、矿业权评估、可行性研究。
