超长探矿斜坡道施工实践

Construction practice of very long prospecting ramp

根据工程特点,将探矿斜坡道按表土层和基岩层分为开口段和基岩段,分别采取不同的技术措施和施工方法。为了施工安全,开口段进行了边坡加固和超前支护,基岩段在特殊地段特别是软弱岩层和断层带也采取了特殊的施工措施。根据严格的测算,配备了合理的掘砌和出碴及运输设备。

According to the characteristics of the engineering and the topsoil and basement rocks,the prospecting ramp was divided into open section and bedrock seetionin,and different technical measures and construction methods were used respectively. For the safety of the construction, the slope solidification and advanced support were carried out in the open section. Special construction measurements were taken on the special parts of basement rocks such as weak rock stratum and fault zone. The suitable equipments of driving and permanent lining, withdrawal of slag and transportation were equipped basing on the strict calculation.
