【摘要】：針對煤層厚度是煤礦鉆孔勘探獲得的準(zhǔn)確性較高數(shù)據(jù),研究了基于鉆孔煤厚數(shù)據(jù)對煤厚分布預(yù)測與構(gòu)造預(yù)判中的作用。以開灤東歡坨礦-690 m水平南翼采區(qū)為研究區(qū),重點(diǎn)分析了煤層厚度數(shù)據(jù)缺失的不同情況,分別基于不含零值與含零值的鉆孔煤厚數(shù)據(jù),應(yīng)用Surfer軟件繪制了5、7與8煤層厚度等值線,對比分析了煤層厚度的空間特征,并推斷了導(dǎo)致煤層缺失的構(gòu)造位置。結(jié)果表明,鉆孔煤層缺失情況普遍存在,由沉積尖滅、構(gòu)造斷失、風(fēng)化剝蝕與鉆孔深度不足等4種原因?qū)е?前2種情況下煤厚應(yīng)視為零值。不考慮零值與考慮零值時(shí),預(yù)測得到煤厚小于0.6 m的不可開采區(qū)分布范圍差別較大。在鉆孔車102/車10—東觀22—車32/車106—車105—車14一帶存在多孔煤厚構(gòu)造斷失,推測沿NW方向展布有斷層構(gòu)造帶。
[Abstract]:In view of the fact that coal seam thickness is the accurate data obtained from borehole exploration in coal mine, the effect of coal seam thickness data on prediction of coal thickness distribution and prediction of structure is studied. Taking the mining area of the southern wing of Donghuantuo Mine at -690 m level in Kailuan River as the study area, the different situations of missing coal seam thickness data are analyzed, respectively, based on the borehole thickness data without zero value and zero value, respectively. Using Surfer software, the thickness isolines of 5 and 8 coal seams are drawn, and the spatial characteristics of coal seam thickness are compared and analyzed, and the structural location that leads to the lack of coal seam is inferred. The results show that the lack of borehole coal seam is generally caused by depositional pinning, structural failure, weathering and denudation, and insufficient drilling depth. The coal thickness should be regarded as zero in the first two cases. When zero value is not considered and zero value is considered, the distribution range of unmined area with coal thickness less than 0.6 m is different greatly. In the area of drilling vehicle 102 / vehicle 1010-Dongguan 22-car 32 / car 106- car 105- car 14, there is a loss of porous coal thick structure, and it is assumed that there is a fault structure belt along the NW direction.
