建设大型现代化矿井通常采用立井开拓的方式,对于冲积层段采用钻井法、基岩段采用地面预注浆的井筒,针对传统施工顺序施工工期较长的问题,通过"十一五"国家科技支撑计划课题"钻-注平行作业关键技术研究及示范工程"的研究,确定了钻井与注浆在时间和空间关系上的设计原则,解决了高精度随钻测斜仪、钻井泥浆受注浆浆液影响的监测等关键技术,在国内外首次实现了注浆与钻井法施工在一定时间和空间内平行作业,可以节省建井工期20%～30%;着重阐述了钻-注平行作业的特点、实现方式、设计原则及其支撑技术。

To build a large modernized mine would have a mine shaft development mode.A mine shaft dillig method would be applied to the alluvium section of th e mine shaft and the surface pre-grouting method would be applied to the base rock section of the mine shaft. According to the long time problems of the traditional con struction sequences, with the study on "the study and demo project of the key technology for the drilling and grouting simultaneous operation" in the 11th Five Years Nat ional Science and Technology Support Program, the design principle of the time and space relationship between the drilling and grouting was set up and the high accur acy inclinometer while drilling, the monitoring and measuring of the drilling mud affected by the grouting liquid and other key technology were solved.It was first at home and abroad that the grouting method and mine shaft drilling method were conducted with a simultaneous operation at the certain time and space.The mine shaft constru ction period could be reduced by 20%30%.The paper in detail stated the features of the drilling and grouting simultaneous operation, the implementation mode, design principle and support technology.
