摘　　要：为降低中马村矿211采区西突水点涌水量,解除矿井水患威胁,总结了以往3次堵水工程实践经验,并结合井下施工空间,决定实施小帷幕动水注浆截流技术。通过切断突水点的过水通道,降低动水的流速及流量,配合地面注浆堵水工程,使211采区西突水点涌水量由408 m^(3)/h降至60 m^(3)/h,为类似条件下的其他矿井治理突水点动水,提供工程依据及经验借鉴。In order to reduce the water inflow at the west water outburst point in No.211 mining area of Zhongmacun Mine and relieve the threat of mine water damage,the practical experience of the previous three water plugging projects was summarized.Combined with the underground construction space,the small curtain dynamic water grouting closure technology was carried out.By cutting off the water channel of the water outburst point,reducing the flow velocity and flow of the dynamic water,and combining with the surface grouting water plugging project,the water inflow of the west water outburst point in No.211 mining area was reduced from 408 m^(3)/h to 60 m^(3)/h,which provided engineering basis and experience reference for other mines to control the water outburst point under similar conditions.
