摘要
为解决将军戈壁二号露天煤矿矿区西北部火烧区边界的探查精度不足的问题,采用水平定向钻孔对火烧区边界进行连续探查,给出了定向钻孔轨迹和开分支孔详细参数及封孔方案,进一步修正了火烧边界,划定了勘探区北部实体煤边界线.
Abstract
In order to solve the problem of insufficient exploration accuracy of the boundary of the burning area in the northwest of Jiangjun Gobi No.2 Open-pit Coal Mine area,the horizontal directional drilling was used for the first time to continuously explore the boundary of the burning area.The directional drilling trajectory,detailed parameters of branch holes,and sealing scheme were provided,and the burning boundary was further revised.The physical coal boundary in the northern part of the exploration area was delineated.
