摘　　要：河台金矿高村竖井延深经专家论证后利用辅助阶段延深方法 ,自行设计突破了原设计院确定的下掘深度 ;采用反复导线测量精确确定井筒中心 ,使用喷锚网支护通过破碎岩层 ,运用钢木组合罐道与上部木罐道紧密对接 ,取得良好的运行效果和经济效益。The deepening of Gaocun vertical shaft of Hetai Gold Mine was completed by digging auxiliary stages to deepen the shaft from below to above.A break through in the design by the mine was made at the depth of digging decided by the original design institute.The shaft center was defined accurately by repeated measurement with conducting wire.The conbined support of grouting anchor wire gauze was adopted so that the shaft digging could get through crushed strata.A much better economic benefit was acquired from the application of steel timber construeted cageway which butted aginst the timber cageway in the upper part of the shaft.
