摘　　要：中煤陕西榆林能源化工有限公司大海则煤矿一号回风立井风硐施工时,采用SP-Ⅲ型拉森钢板桩控制凿井井架基础位移、风硐井点降水施工技术,有效实现了厚风积沙层基坑边坡稳定,保证了风硐基坑的安全垂直开挖,为类似地层矿井风硐施工积累了丰富经验。SP-Ⅲ Larsen steel sheet pile is used to control the displacement of shaft foundation and the dewatering of shaft point during the construction of air cave in No.1 return shaft of Haize coal mine of Shaanxi Yulin Energy and Chemical Co.,Ltd.,which effectively realizes the stability of foundation pit slope in thick aeolian sand layer,ensures the safe vertical excavation of air cave foundation pit,and accumulates rich experience for the construction of air cave in similar strata。
