摘要
介绍了在老矿区深部进行找煤所采用的工艺与方法,即在采空煤层井段采用风动潜孔锤钻进方法进行施工,在钻穿采空煤层后在深部采用绳索取心钻进方法施工。对施工中遇到的技术问题所采用的方法及取得的经验与教训进行了阐述。
The paper introduced the technologies and the methods for deep coal prospecting in old mine, that is after drilling through mined out section with pneumatic down hole hammer, the wire-line coring drilling is used in deep construction. The technical problems encountered in the construction and the experiences obtained were discussed.
