【摘要】：为避免在复杂水文地质条件下使用单一判别方法判定突水水源的误判,提出多方法多途径综合研判突水水源方法,以王楼煤矿13301工作面突水为例,因突水过程中上覆侏罗系(J_3)砂岩含水层水位异常性同步下降,据此认为J_3砂岩含水层为突水水源,按照分析→验证→再分析→再验证的技术路线,采用水化学联通试验、注浆试验、水质分析、TVL雷达探测、富水性评价等多种方法和手段综合研究,最终查明J_3砂岩含水层与工作面之间没有水力联系。综合研判方法结果表明:由于管涌通道和压力自然平衡作用导致J3砂岩水位异常下降;煤层顶板砂岩(3砂)含水层才是唯一的突水水源,只能疏排不可封堵,采用多手段多途径综合研判方法能够避免误判问题。
[Abstract]:In order to avoid using a single discriminant method to judge the miscarriage of water in water inrush under complex hydrogeological conditions, a multi method and multi way method is proposed to judge water inrush from 13301 working face in Wang Lou coal mine as an example. The water level of the overlying Jurassic (J_3) sandstone aquifer in the process of water inrush is decreased synchronously, according to which the J_3 sandstone aquifer is considered. For water inrush water source, according to the technical route of analysis, verification, re analysis and re validation, a comprehensive study of various methods and means, such as hydrochemical interconnection test, grouting test, water quality analysis, TVL radar detection, water rich evaluation and so on, has been studied. Finally, there is no hydraulic connection between the aquifers and the working surface of the J_3 sandstone. The results of the comprehensive evaluation show that: Due to the natural balance of piping and pressure, the water level of J3 sandstone is abnormally reduced, and the sandstone (3 sand) aquifer of coal seam roof is the only water inrush source, which can only be blocked and can not be blocked. The problem of misjudgement can be avoided by using multi means and multi way comprehensive evaluation method.
