由于矿井顶板含水丰富,回采期间矿井最大涌水量达到900m3/h以上。为了实现安全回采,回采前期研究工作面顶板含水层地下水赋存特征,探查验证顶板物探结果,判断含水层对工作面开采时的影响程度,并通过放水试验进一步获取含水层相关水文地质参数,获取含水层涌水量、水位随时间等变化规律,为工作面及采区顶板水疏放工程优化布局提供科学依据。通过探查及放水实验孔数据实测,最终确定工作面疏放水方式,有效地降低工作面水害的威胁程度,确保了工作面回采后的安全生产。
由于礦井頂闆含水豐富,迴採期間礦井最大湧水量達到900m3/h以上。為瞭實現安全迴採,迴採前期研究工作麵頂闆含水層地下水賦存特徵,探查驗證頂闆物探結果,判斷含水層對工作麵開採時的影響程度,併通過放水試驗進一步穫取含水層相關水文地質參數,穫取含水層湧水量、水位隨時間等變化規律,為工作麵及採區頂闆水疏放工程優化佈跼提供科學依據。通過探查及放水實驗孔數據實測,最終確定工作麵疏放水方式,有效地降低工作麵水害的威脅程度,確保瞭工作麵迴採後的安全生產。

Because the water is rich in mine roof, the mine largest water inflow has reached more than 900m3/h. In order to realize safe mining, study the occurrence characteristics of groundwater in work face roof, exploration and verification of roof geophysical exploration results, judge the influence degree of aquifer to exploit of work face, and acquire relevant hydrogeologi-cal parameters of aquifer, and change rules that aquifer inflow, water level variation with time, to provide the scientific basis for the working face and the mining roof water drainage engineering layout optimization. Through the exploration and data actu-al measurement of water experiment hole, eventually determine the working surface drainage, reduce the threat level of working face effectively, to ensure safe production after face mining.
