寺河矿厚层综采工作面覆岩冒裂带发育高度实测研究

Field Research on Developing Height of Overlying Strata Overlying Strata of Thick Layer Fully-mechanized Mining Working Face in Sihe Mine

厚煤层综采工艺引起的覆岩顶板导水裂缝带发育规模直接影响防治水安全评价结果。以晋城寺河矿为例,采用冲洗液消耗量法、钻孔彩色电视观测法和RFPA数值模拟法对3#煤顶板导水裂缝带进行了深入研究,研究成果对晋城矿区类似条件的矿井具有借鉴意义。

Devloping scale of overlying strata roof water flowing fractured zone caused by thick coal seam full-mechanized mining technique effects water control safety evaluation results directly. Taken the Sihe Mine at Jincheng as an example, research was done on 3^# coal roof water flowing fractured zone by using consumption of rinsing liquid method, drill hole colour television observation method and RFPA. The research results provide reference significance for mine of similar condition in mining area of Jincheng.
