- 摘要:
- 为研究干旱地区煤矿开采对地表土壤理化性质的影响，分别在煤矿开采前、中、后对开采区地表土壤含水率、土壤有机质含量、土壤密度及土壤机械组成进行了研究。结果表明：在煤层开采前，开采区地表土壤含水率与土壤孔隙度相关，相关系数为0.70，但相关性并不显著，地表土壤水分与其他土壤物理性质基本无关。在沉陷盆地形成过程中，开采区地表土壤水分相比开采前减小1.22%～1.93%，平均减小为1.52%；土壤孔隙度显著增大，土壤有机质含量略微降低，土壤机械组成基本没有变化。地表土壤含水率与其他土壤理化性质均有不同程度的相关性，但相关性均不显著。在沉陷盆地形成稳定后，沉降盆地中心位置地表土壤含水率逐渐恢复甚至大于未开采前，沉降盆地边缘位置地表土壤含水率一直处于减小状态，沉降稳定后土壤孔隙度相比开采前有所增大，土壤有机质含量基本不变，土壤粉粒含量显著增大，土壤黏粒含量降低，地表土壤水分含量与土壤孔隙度呈正相关关系。
- Abstract:
- In order to study the influence of coal mining on the physical and chemical properties of surface soil in arid areas, the soil moisture content, soil organic matter content, soil density and soil mechanical composition of the mining area before, during and after coal mining were investigated. The results show that before the coal mining, the surface soil moisture content in the mining area is related to soil porosity, the correlation coefficient is 0.70, but the correlation is not significant, the surface soil moisture is basically independent of other soil physical properties; in the formation process of subsidence basin, the surface soil moisture in the mining area decreased by 1.22%~1.93% compared with that before mining, and the average reduction was 1.52%; the soil porosity increased significantly, the soil organic matter content decreased slightly, and the soil mechanical composition was basically no change. The soil moisture content of the surface has correlation with other soil physical and chemical properties to some extent, but the correlation is not significant. After the subsidence basin is stabilized, the surface soil moisture content in the central part of the subsidence basin gradually recovers and is even greater than that before coal mining. The surface soil moisture content at the edge of the subsidence basin has been decreasing. After the settlement is stabilized, the soil porosity increased compared with that before coal mining. The soil organic matter content is basically unchanged, the soil silt content significantly increases, the soil clay content decreases, and the surface soil moisture content is positively correlated with soil porosity.
