摘要
为解决淮北矿业集团桃园煤矿新副井井筒在老工业广场冲积层中冻结法凿井的技术难题,在施工过程中对外层井壁的受力和温度进行了实时监测,获得了老工业广场内复杂地质水文条件下井壁受力和温度的实测数据,通过实测信息反馈,实现了矿井动态设计和信息化施工。
In order to solve the technical problems of freezing shaft in alluvium to Huaibei Taoyuan coal mine in old industry square, in site measurements of force and temperature impact of the out wall of mine shaft lining were conducted during the shaft sinking. The site measured data of freezing clay pressure in old industry square were obtained where hydrogeology is complicated. After the information feedback, a dynamic design and informational construction was made for the shaft.
