深井接地在岩石丘陵地区的应用与探讨

Application and Discussion on Deep Well Grounding in Rock Hilly Areas

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。

In 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＆#39;t satisfy the design specification requirement of horizontal ground-ing 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.
