摘要
以淮北矿业股份公司桃园煤矿北六大巷为研究目标,分析了北六大巷在7246、8246工作面骑跨采影响下巷道围岩矿压显现特征。根据实测资料对巷道受采动影响的变形规律、破坏特征进行了分析。借助于数值模拟方法,分析了骑跨采动压巷道在煤层工作面回采时的稳定性特征,得到了巷道围岩应力及塑性区范围等。
Taking north-six roadway of Taoyuan Coal Mine,Huaibei Mining Group as the research target,this paper analyzes surrounding rock pressure appeared characteristics under the influence of the north-six roadway by riding mining 7246 face and 8246 face.According to the observed data,analyzes the deformation rule and destruction features effected by mining roadway.With the help of numerical simulation,the stability characteristics of roadway affected by riding mining in coal seam mining are analyzed and obtains the surrounding rock stress and plastic zone range.
