便携式钻机在水泥灰岩矿勘查中的应用

Application of the Portable Drill in Cement Limestone Ore Exploration

便携式钻机已广泛应用于地质与工程勘查中,为了进一步扩大便携式钻机的应用范围,倡导绿色勘查,在湖南省东安县王师岭矿区水泥灰岩矿勘查中,采用ZY-25型便携式钻机以钻代槽进行地表取样,取得了较好的效果。应用实践表明,当矿区构造简单,岩层产状较平缓且稳定,矿体厚度较大,矿石有用组分含量较高且分布均匀,有害组分含量较低时,采用便携式钻机取样代替槽探取样评价矿床是可行的。

Portable drill has been widely used in geology and engineering exploration, in order to further expand its applica- tion scope and advocate green exploration, in Wangshiling cement limestone ore exploration of Dong＇ an County, the sam- ples were obtained by using ZY - 25 type portable drill by drilling instead of trenching with good effect. The practical appli- cation shows that under the conditions of simple mining area structure, gentle and stable strata occurrence, large thickness of ore body with high and uniform content of useful mineral components and low content of harmful components, it is feasi- ble to use portable drill for sampling by drilling instead of trenching.
