【摘要】：為了查明影響含煤地層巖石吸水性的主要影響因子及其對(duì)于巖石吸水性的影響關(guān)系,在陜北杭來(lái)灣煤礦含煤地層取巖樣,根據(jù)巖樣的水理性質(zhì)測(cè)試及X射線衍射試驗(yàn)數(shù)據(jù),通過(guò)灰色關(guān)聯(lián)分析及逐步回歸分析對(duì)巖石吸水性的影響因子進(jìn)行對(duì)比分析,結(jié)果表明:孔隙度及伊利石、高嶺石、鉀長(zhǎng)石、綠泥石、斜長(zhǎng)石的礦物含量為巖石吸水性的主要影響因子;利用逐步回歸分析方法建立了巖石吸水性的回歸方程,精度較高,可以較好地反映該礦區(qū)含煤地層巖石的吸水性與其主要影響因子之間的量化關(guān)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.
