【摘要】：針對因鉆孔單位涌水量數(shù)據(jù)嚴(yán)重不足而無法評判整個(gè)井田奧灰含水層富水性的實(shí)際情況,選取了新汶煤田良莊井田井下奧灰水文孔鉆孔涌水量、影響煤層安全開采的奧灰上部馬家溝組上段含水層厚度、井田內(nèi)斷層分維值、井田內(nèi)褶皺分維值和奧灰上部峰峰組含水層深度5個(gè)影響因素,作為評價(jià)奧灰富水性的指標(biāo),采用主成分分析法從這5個(gè)因素中提取出主控影響因素并獲得對應(yīng)的權(quán)重,建立了富水性指數(shù)的數(shù)學(xué)模型。通過確定分區(qū)閾值,繪制了以富水性指數(shù)為依據(jù)的良莊井田奧灰富水性分區(qū)圖,為煤礦的安全開采提供基礎(chǔ)資料。
[Abstract]:In view of the fact that the water abundance of Ordovician ash aquifer can not be judged because of the serious shortage of drilling unit water inflow data, five influencing factors, namely, the thickness of aquifer in the upper section of Majiagou formation, the fractal dimension value of fault in well field, the fractal dimension value of fold in well field and the depth of aquifer in the upper peak formation of Ordovician ash in Liangzhuang coalfield, Xinwen coalfield, are selected, which affect the thickness of aquifer in the upper Majiagou formation of coal seam safe mining, the fractal dimension value of fold in well field and the depth of aquifer in the upper peak formation of Ordovician ash. As an index to evaluate the water enrichment of Austrian ash, the main control influencing factors are extracted from these five factors by principal component analysis (PCA), and the corresponding weights are obtained, and the mathematical model of water enrichment index is established. By determining the partition threshold, the water-rich zoning map of Ordovician ash in Liangzhuang mine field based on water-rich index is drawn, which provides the basic data for the safe mining of coal mine.
