立井井筒快速施工技术研究

Technology researching of fast construction of the pit shaft in standing well

重点介绍了立井快速施工的机械化配套原则、中深爆破掏槽方式及其参数的选择、光面爆破参数的确定、混凝土搅拌方式及输料方法和加强施工组织管理等措施,通过这些关键技术在工程实践中应用获得了较快的施工速度,从而缩短建井工期,节约工程成本。

This text has introduced the principle of in the mine＇s construction,the way of undermine blasting in mid-depth and the selection of its parameters,the confirmation of the parameters in smooth blasting,the way of concrete batching and its diverging way,and the enhance of construction management. Through these key technologies have achieved the faster construction progress in engineering practice,so that to shorten the construction period of well building and save the project cost.
