北宿煤矿构造组合及其对煤层的控制作用

Structural compounding and controlling to coal bed of Beisu mine

基于北宿煤矿煤田地质勘探资料,从矿井构造组合的角度分析了该矿构造组合的特征及其对煤层的控制作用。北宿煤矿地质构造主要以断层为主,按其走向和性质可分为两组:一组走向NW,为正断层;另一组走向NE或NNE,为逆断层。此外,该煤矿还发育褶皱和节理。各构造相互组合和叠加,控制着矿区煤层的赋存状态。

Structural compounding and controlling to coal bed of Beisu mine were analyzed according to the data collected from the original geological exploration.Faults were the main geological structure in Beisu mine.They could be divided into two groups according to the strike and character.One was normal fault with NW strike;the other was reverse fault with NE or NNE strike.In addition,folds and joints were also developed in the mine.Different structures compounded and superposed each other;they controlled the form of mine bed of Beisu mine.
