1987年煤炭部技术发展司在邯郸矿务局召开了“电测深方法在煤矿防治水中的应用技术鉴定会议”。与会代表认为,邯郸矿务局承担的这一科研项目达到了原计划任务书的要求,在国内首次将地面直流电测深技术应用于煤矿井下,在探测隔水层厚度、导升高度等方面取得了明显效果,因此通过了技术鉴定。
In 1987, the Ministry of Coal Industry Technology Development Division convened the “Technical Appraisal Meeting of Electrical Sounding Method in Coal Mine Water Prevention and Control” in Handan Mining Bureau. Delegates at the meeting held that this research project undertaken by Handan Mining Bureau had met the requirements of the original plan and task statement and that for the first time in China the surface direct current sounding technology was applied to coal mines for obtaining the thickness of the aquitard and the height of the guide risers The obvious effect, so adopted the technical appraisal.
