摘　　要：岩溶水水害是影响准格尔煤田安全开采的关键因素之一,为了掌握岩溶发育特征、水化学特征、渗流场特征及突水危险性,通过钻探、水文勘查及水化学试验等区域资料对其进行了深入研究。研究结果表明:岩溶裂隙、溶孔和溶洞是主要储水空间和地下水径流通道,陷落柱、断层是该区域重要的垂向导水通道;沿径流途径岩溶水质类型呈HCO3·Cl-Na→HCO3·Cl-Na·Ca(Ca·Mg)→Cl-Na的演化顺序,反应了在东部边界黄河水补给地下水,岩溶地下水总体向西运移,在煤田西部形成滞流区;煤田中东部6号、9号煤均处于非带压开采状态,中西部处于带压开采状态,滞流区边界附近突水系数较大。在岩溶含水层水文地质特征研究基础上,提出了探测、预测及监测和治理与特殊开采等水害综合防治技术体系。The hazard of karst water is one of the key factors affecting the safety of mining in Zhungar Coalfield. In order to master karst development characteristics, hydrochemical characteristics, seepage field characteristics and water inrush risk, the analysis was carried out comprehensively by the regional data of drilling, hydrological exploration and hydrochemical experiment.The analysis indicates that karst fissures, karst holes and karst caves are the main water storage space and groundwater runoff channels, and collapse columns and faults are important vertical water conducting channels in this area. The evolution sequence of karst water quality type along the run-off path is HCO3·Cl-Na→ HCO3·Cl-Na·Ca（Ca·Mg）→Cl-Na, which indicates that the Yellow River water supplies groundwater at the eastern boundary, and karst groundwater generally moves westward, forming a stagnating area in the west of coalfield. The analysis also shows that No. 6 and No. 9 coal in the middle and eastern part of the coal field are all in non-belt pressure mining state, and the western coal field is in pressure state. The water inrush coefficient is large near the border of stagnating zone. Based on the study of the hydrogeological characteristics of karst aquifer, a comprehensive technical system for the prevention and control of water hazards such as detection, prediction, monitoring, control and special mining is proposed.
