e.将井壁磨损检测器1提升至井口，相对原来位置沿井筒圆周方向旋转45°，再次重复步骤a～d；
d0为投料井磨损前的井壁内径，△d为通过微调螺母15调节损伤探测头16可以增加的井壁磨损检测器1外圆直径，d为井壁磨损检测器1准备进入投料井内时的外圆直径，m0为井壁磨损检测器1准备进入投料井内时水平位移测量器5的初始读数，n0为井壁磨损检测器1准备进入投料井内时垂直位移监测器3的初始读数，h为井壁磨损检测器1与井口的距离结合垂直位移监测器检测数据和水平位移测量器收集的数据以及水平位移测量器5的初始读数m0和垂直位移监测器3的初始读数n0，可以将某一方位角度井壁沿垂直方向的磨损曲线画出。
实施例二：固体充填投料井井壁磨损检测装置还包括旋转控制装置，所述限位导杆2一端与井壁磨损检测器1的连接方式为水平可旋转连接，所述旋转控制装置的信号输出端与井壁磨损检测器1的信号输入端连接，通过旋转控制装置可以控制井壁磨损检测 器1在井壁底水平旋转，当井壁磨损检测器1进入井内完成第一次检测后，在不需要取出井壁磨损检测器1的情况下，在井底通过旋转控制装置旋转井壁磨损检测器1转动45°后，逐渐往上取出的同时，井壁磨损检测器1从井中取出的过程“顺便”完成另一方位角度井壁磨损情况的检测，操作上更加简便快捷。
以上所述仅是本发明的优选实施方式，应当指出：对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
