摘要
为评价与防治顶板水害,研究导水裂缝带的发育特征,以高庄煤矿3上1110和3上509工作面为例,分析了工作面开采期间顶板微震事件分布的时空规律,结合现场实测结果综合确定了导水裂缝带发育高度,克服了单一研究方法的局限性。研究表明,高庄煤矿采动工作面导水裂缝带高度约为50 m。煤层顶板导水裂缝带发育高度的认识对矿井顶板水害防治工作具有重要意义。
Roof water disasters is an important threat to the safety of coal mining,and the study on the development characteristics of the water-conducting fracture zone is an important content to evaluate and prevent roof water damage.Taking the 1110 working face and 509 working face of Gaozhuang coal mine as an example,this paper analyzes the spatiotemporal law of the distribution of microseismic events on the roof during the mining period of the working face,and determines the development height of the water-conducting fracture zone by combining field measurement,overcoming the limitation of a single research method.The result shows that the height of the water-conducting fracture zone of Gaozhuang coal mine is about 50 meters.It is of great significance to know the development height of the water-conducting fracture zone on the roof of coal seam for the prevention and control of water damage on the roof of coal mine.
