摘要
印度尼西亚WBM煤矿目前在浅部进行露天开采,采深已超过160 m,计划将露天开采转为井工开采。但钻井资料显示该区地温普遍较高,地温灾害是井工开采的主要灾害之一。根据已有的10个钻孔温度资料,利用数理统计及插值法估算了矿井地温梯度,并绘制了地温分布图,对矿井首采区的选择和设计生产提出建议,为矿井今后的开发建设提供了参考。
WBM Mine is open-pit mining at the shallow part. Mining depth is more than 160 m. It plans to turn open-pit mining into underground mining. But the drilling data show that the geothermal is generally high. Geothermal disaster is one of the major disasters of underground mining. According to the temperature data of 10 boreholes,this paper had estimated geothermal gradient,drawn the map of temperature distribution,and provided recommendations for the selection of first mining area,design and production. It provides a reference for mine development and construction in the future.
