摘要(Abstract)：
采用深孔牙轮钻机、利用高台阶崩落法成功地处理了复合采空区,解决了复合采空区处理难的问题,使技术人员在熟练浅采、深采空区处理的情况下,又探索出复合采空区的处理方法。为矿山的发展消除了安全隐患,扫清了前进的障碍;为同类矿山的空区处理及相关问题的探讨提供了参考依据。
The paper introduced the successful application of high bench caving method of using deep hole roller rock bit into the practice of solving the complex goaf area,a stuff problem of this kind.The successful application of this technique has made the technical staffs find their way of treating complicated goaf area under the circumstances of shallow and deep mining with their skill.Also the new treatment contributed safety operation to the mine's development and offered valuable reference to the similar mine facing the same problem.
