超前工作面区域复合顶板应力分布规律研究

Research on stress distribution law of compound roof in advance working face area

为确定综采工作面合理长度,提高工作面生产能力及效率,本文通过对鹿台山煤业2号煤层超前工作面区域复合顶板应力分布规律进行分析,并根据临近的2202工作面初采期间的矿压监测情况,结合工作面顶板实际地质情况,通过理论计算得出了2203工作面所能布置的最大工作面长度,研究结论对提高该矿安全高效生产能力具有积极的理论意义。

For the sake of ascertaining the mining face rational length and improving the producing capacity and efficiency,this paper analyzed the distribution of strain of the compound mining roof in the advanced area of No.2 coal seam working face in Lutaishan coal industry,and according to the monitoring of ore pressure during the initial mining of the adjacent 2202 working face.According to the mining pressure monitoring results of adjacent 2202 working face during primary mining time and the roof geological conditions of 2203 working face,it calculates the rational length of 2203 working face,which is important to further improving the producing capacity and efficiency of this coal mine.
