基于微震监测的重复采动煤层潜在导水通道形成规律研究
Study on the formation law of potential water conducting channel in repeated mining coal seam based on microseism monitoring
摘要
Abstract
In order to avoid the occurrence of water outburst accidents in deep coal seam mining,the formation law of potential water conducting channels in the floor during the mining process of repeated mining face was explored.Taking No.Ji 17-33200 Face of No.10 Mine of Pingdingshan Tian'an Coal Industry Co.,Ltd.as the engineering background,20 geophones were arranged in the'Meihua'type in the two roadways to form a fully enclosed monitoring array to continuously,real-time and dynamically monitor the working face.The microseism technology was used to analyze the failure law of the plastic zone of the overlying strata and the deep microseism events of the floor during the repeated mining of the lower coal,and the formation law of the potential water conducting channel was explored in combination with the theoretical calculation.关键词
