区域探查治理技术在构造治理方面的应用及效果验证

Application and effect verification of regional explorationand control technology in structure control

构造导致底板突水是常见的矿井水害形式之一,井下治理难度大且费用较高。本文以顾北矿区域探查治理为例,介绍了区域探查治理技术在构造治理方面应用的技术方案、实施过程和效果验证,通过施工43个定向水平分支孔进行超前区域探查并实施高压注浆。结果表明,地面区域探查治理技术相比井下治理施工风险小,注浆压力高,验证治理效果良好,为采区安全回采提供了依据。

Floor water outburst caused by structure is one of the common forms of mine water damage,and underground control is difficult and expensive.Taking the regional exploration and control of Gubei Mine as an example,this paper introduced the technical scheme,implementation process and effect verification of regional exploration and control technology in structural control.Through the construction of forty-three directional horizontal branch holes,advanced regional exploration and high pressure grouting were carried out.The results showed that the ground area exploration control technology had less risk,higher grouting pressure,and better control effect than underground control construction,which provided a basis for safe mining in mining area.
