涞源龙门金多金属矿普查绿色勘查实践

Field test of the green exploration concept in Laiyuan County Longmen gold polymetallic mine general surney

摘要:

河北省涞源县龙门金多金属矿普查工作，贯彻绿色勘查理念，对槽探工程、老硐清理、钻探工程按《绿色勘查指南》进行了专项设计并付诸实施。槽探工程施工挖掘的腐植土和碎石就近分开堆放并遮盖，待项目验收合格后，回填腐植土和碎石，最后平整并绿化；老硐清理出的碎石选择离硐口较近的相对平坦的地方堆放，并做好防护工作，最后覆土绿化；钻进工程采用清水和环保泥浆做冲洗液，金刚石单管和绳索取心钻进，提高了效率，减少了对地质环境的影响。机台建设占地少，施工过程中避免油污等的外溢，项目竣工验收后地貌恢复采用植草、自然恢复等绿化方法。绿色勘查充分贯彻了绿水青山就是金山银山的绿色发展理念。

Abstract:

The concept of green exploration is implemented in the survey work at the Longmen gold polymetallic mine in Laiyuan County, Hebei Province, where special design is carried out for trench exploration, old tunnel cleaning and drilling as per the “Green Exploration Guideline” standard. Humus soil and rubbles dug out during trenching exploration are piled and covered separately. After the project is accepted, humus soil and rubbles are backfilled, compacted and greened; the rubbles removed from the old tunnel is piled a flat place close to the tunnel, and well protected, and then covered with soil and greened; clean water and envionmental protection mud are used as the drilling fluid for drilling projects, with diamond drilling and wireline coring as the drilling process; thus improvingdrilling efficiency, reducing impact on the geological environment with less drilling rig footing, and eliminatingoil spillage during construction. After completion of the project, the landscape is reinstated through grass planting and natural restoration. Green survey implements fully the green development concept that green mountains and clean water are the gold and silver mountain.
