摘要

煤层底板石灰岩含水层是煤层底板突水的主要来源,严重威胁着煤矿开采安全。为了减少和避免煤矿突水的发生,我们采用了地球物理勘探技术、钻井技术、突水事故和示踪试验等多种探测技术,对平顶山煤炭有限责任公司潮川矿一井岩溶发育进行了多方位探测,分析了岩溶发育特征,中国河南省。结果表明,寒武纪灰岩岩溶水较差;存在一定的液压连接。在F5、F1、SF28断层附近,为少富水区,水性较弱,深层岩溶水形成封闭区;太原石灰岩和CL岩溶浅层突水事故中,61.54%是由大型构造和附近浅层断裂引起的。岩溶垂直分带较浅;在海拔140m以上和-150m以下,1号井西翼的浅水水位下降幅度大于东翼。F125水位下降幅度比东翼大,西断层由于岩溶水的水力连接侵入屏障翼而超过170m。-150m F125断层下方的东翼在水力连接两侧都是软弱和不均匀的。

Analysis of the karst development law based on multiple exploration technologies of Cambrian limestone
Coal mine floor limestone aquifers are a major source of water inrush from the coal seam floor and a serious threat to the safety of coal mining. In order to reduce and avoid the occurrence of water inrush within the coal mine, we use multiple detection techniques, which are geophysical exploration technology , drilling technology, water inrush accidents and tracer test, to develop a multi-faceted exploration of karst development and analyze its development characteristics in the Chaochuan mine No. 1 well of Pingdingshan Coal Co.Ltd, Henan Province, China. The results show that, the Cambrian limestone (CL) karst water is poor; there is a certain hydraulic connection. Near faults F5, F1, and SF28, the area is less water-rich area, the water is weak, and the deep karst water forms a closed area; 61.54 % of shallow water inrush accidents in the Taiyuan limestone and CL karsts were caused by large tectonic and nearby shallow faults. The karst vertical zonation is shallow; the shallow water level decreased more in the West Wing of the No. 1 well than in the East Wing at elevations above 140 m and below -150 m. The F125 level decline is greater than that of the east, and the west fault is more than 170 m due to the hydraulic connection intrusive barrier wings of the karst water. the East Wing below -150 m F125 fault was weak and uneven on both sides of the hydraulic connection.

期刊介绍: Scientific Mining Journal, which is published i n open access electronic environment and i n printed, is a periodical scientific journal of Union of Chambers of Turkish Engineers and Architects Chamber of Mining Engineers. The name of the journal was "Mining" until June 2016 and it has been changed to "Scientific Mining Journal" since September 2016 because it can be confused with popular journals with similar names and the ISSN number has been updated from 0024-9416 to 2564-7024. Scientific Mining Journal, published four times a year (March-June-September-December), aims to disseminate original scientific studies which are conducted according to the scientific norms and publication ethics at national and international scale, to scientists, mining engineers, the public; and thus to share scientific knowledge with society. The journal is in both Turkish and English. The journal covers theoretical, experimental, and applied research articles, which reflects the findings and results of an original research i n the field of mining engineering; review articles, which assess, evaluates, and interprets the findings of a comprehensive review of sufficient number of scientific articles and summarize them at present information and technology level; technical notes, which may be defined as a short article that describes a novel methodology o r technique; a case studies, which are based on the theoretical o r real professional practice and involves systematic data collection and analysis.
