【摘要】：为了查明影响含煤地层岩石吸水性的主要影响因子及其对于岩石吸水性的影响关系,在陕北杭来湾煤矿含煤地层取岩样,根据岩样的水理性质测试及X射线衍射试验数据,通过灰色关联分析及逐步回归分析对岩石吸水性的影响因子进行对比分析,结果表明:孔隙度及伊利石、高岭石、钾长石、绿泥石、斜长石的矿物含量为岩石吸水性的主要影响因子;利用逐步回归分析方法建立了岩石吸水性的回归方程,精度较高,可以较好地反映该矿区含煤地层岩石的吸水性与其主要影响因子之间的量化关系。
[Abstract]:In order to find out the main factors affecting the water absorption of the coal bearing strata and their relationship to the water absorption of the rocks, rock samples were taken from the coal bearing strata of Hanglewan Coal Mine in Northern Shaanxi Province, and according to the test data of the hydraulic properties of the rock samples and the X-ray diffraction test data, By means of grey correlation analysis and stepwise regression analysis, the influence factors of rock water absorption were compared and analyzed. The results showed that porosity and Illite, kaolinite, potassium feldspar, chlorite, etc. The mineral content of plagioclase is the main influencing factor of rock water absorption, the regression equation of rock absorptivity is established by stepwise regression analysis, and the accuracy is high. It can better reflect the quantitative relationship between the water absorption of coal bearing strata and its main influencing factors.
