摘要 

采动工作面对上覆岩层的影响范围直接关系到煤矿的安全生产,为了准确测定回采工作面“三带”顶界面发育高度,采用井下钻孔电阻率法探测了回采工作面不同时刻不同深度的视电阻率值,探讨了不同采动位置与基准位置的视电阻率差值断面图,分析了“三带”发育的的岐离率曲线,确定了各带的顶界面发育高度,并与双端封堵分段注水法推导公式计算结果进行了比较。结果表明:钻孔电阻率法对井下复杂环境的干扰抵抗能力强,与煤岩层耦合性很好,采用视电阻率差值确定的“三带”顶界面发育高度精度较高;由岐离率曲线确定的冒落带顶界面发育高度为29.6 m,裂隙带顶界面发育高度为47.8 m,弯曲带顶界面发育高度为71 m,其结果与双端封堵分段注水探测结果相近,岐离率可明显区分“三带”的分界面,提高了“三带”顶界面发育高度探测的分辨率,具有较高的推广实用价值。

Abstract

The influence range of the mining work on the overlying rock strata is directly related to the safe production of the coal mine. In order to accurately determine the development height of the "three zones" top interface of the mining face, the author used the mine drilling resistivity method to detect the different depths of the mining face at different periods. The sectional view was used to explore the apparent resistivity cross value between different mining positions and the reference position. The deviation rate curve of the "three zones" development was analyzed. The development height of the top interface of each zone was determined. And the results were compared with the calculation results by the derivation formula of the double-end plugging segmental water injection method. The results show that the borehole resistivity method has strong resistance to the complex environment of the underground, and has good coupling with the coal-rock layer. The height of the "three-band" top interface determined by the difference of apparent resistivity is higher. The determinations by the deviation rate curve are as follows: The development height of the top of the falling zone is 29.6m, the development height of the top interface of the fracture zone is 47.8m, and the development height of the top of the curved zone is 71m. The results are similar to those of the double-ended plugging water injection, and the deviation rate can be clearly distinguished. The interface of the three belts improves the resolution of the height detection of the "three belts" top interface, and has a high promotion and practical value.
