摘要
赵楼煤矿副井冲积层厚度475 m,是巨野矿区代表性的深厚表土井筒。通过现场实测,获得赵楼煤矿副井井壁表土基岩交界面3个层位近4 a的应变数据,通过每个层位4个方位最大值与此层位的历史最值作比较,对矿井安全作出初步判断。成果对于研究巨野矿区深厚表土层井壁变形规律具有重要的参考价值。
The thickness of alluvial layer of Zhaolou coal mine is 475 m,which is the representative surface well of Juye mine area. Through the field measurement, the strain data of Zhaolou coal mine are obtained in the past four years at the interface between topsoil and bedrock. By comparing the maximum value of each layer with the historical maximum of this layer, a preliminary judgment is made on shaft safety. The results are important value for studying the deformation rules of deep wall in Juye mining area.
