摘要在矿山基本建设中，矿区变电所、风井场地及瓦斯抽放泵站等建(构)筑物一般建设在山区上，该区域气候干燥，雨水少，地质以岩石为主，场区传统的水平式接地网接地电阻满足不了设计规范要求，故如何降低场区接地电阻，长期有效地保证场区设备及人身安全，显得尤为重要。介绍了岩石丘陵地区的室外防雷接地施工应用情况，通过实例对垂直式深井接地与传统的水平式接地的实用性进行了比较，验证了岩石地区采用深井接地的经济性和可靠性，符合国内岩石丘陵地区室外接地网施工、改造的发展趋势。

AbstractIn the basic construction of coal mine, the buildings such as mine substation, ventilation shaft site, gas drainage pumping station and others are usually in the mountains area. The climate of the region is dry and less rain, rock is the main geology. In the areas, it can't satisfy the design specification requirement of horizontal grounding network grounding resistance in tradition, so it is particularly important that how to reduce the ground resistance and chronically and effectively ensure the safety of equipment and person in court areas. Introduces the application situation of outdoor lightning protection construction in rock hilly region. The practicability of vertical deep well grounding and horizontal grounding in tradition are compared by living example. Verifies the economy and reliability of deep well grounding in rock hilly region, it conforms to construction and reconstruction trend of outdoor grounding grid in domestic rock hilly region.

在矿山基本建设过程中，矿区的变电所、风井场地及地面瓦斯抽放泵站等建(构)筑物一般建设在矿区井田区域的山区上，该区域气候干燥，雨水少，地质以岩石为主，地面表皮软土厚度约为100 mm，碎石结合体厚度约为1 000 mm，土壤层较薄，对水、气隔绝能力较差，水分挥发向下渗透较为严重，降雨时上层滞水，即从地面流失，雨过天晴，土壤很快变干。场区传统的水平式接地网接地电阻满足不了设计规范要求，因此，采取何种接地施工方法，降低场区接地电阻，长期有效地保证场区设备及人身安全，显得尤为重要。……
