摘要
北京大安山煤矿地表只有少数钻孔控制到+550 m水平,为探明下部煤层赋存条件,提高资源储量级别,应用ZDY1000G型全液压坑道钻机、S75绳索取心钻进工艺进行了硐内深孔钻探,完成了坑道内试验钻探孔深505.17 m。随之在2012-2014年共计钻探进尺8237 m,勘探增加资源储量1877.7万t。深孔钻探技术不仅加快了对深部水平煤层的勘探,探明了深部水平煤层赋存条件。为开拓工程部署提供了可靠的地质资料,而且减少了巷探成本,提高了工程效率。本文对井下硐内深孔钻探进行了介绍。
Only a few boreholes in Beijing Daanshan Coal Mine were controlled to the level of +550 m. In order to explore the occurrence conditions of deeper coal seams and improve the magnitude of order of resource reserves, a ZDY1000 G full-hydraulic tunnel drill rig and S75 wire-linecore drilling technology were used to carry out deep hole drilling in the adit. The test drilling depth in the tunnel was 505.17 m. Subsequently, from 2012 to 2014, the total drilling amount was 8237 m, resulting in an increase in the resource reserves by 18.777 million tons through exploration. On the one hand, the deep hole drilling technology can accelerate the exploration of deep horizontal coal seams, and define the occurrence condition of deep horizontal coal seams, which provide reliable geological data for the development of the project. On the other hand, it also reduces the cost of tunnel exploration and improves the efficiency of development. In this paper, the deep hole drilling in the tunnel is introduced.
