一、地质概况龙山矿边界东以F165,西以F174,F172,南至煤层露头的老窑边界,北至-500为界,西,南两面受奥陶系灰岩控制,东北部可向下延深.地层走向由北偏东逐渐转为南东,乃至东西向,状似簸箕倾向北东,倾角9°30～27°40。 First, the geological overview Longshan mine boundary east of F165, west of F174, F172, south to the coal outcrops of the old kiln boundary, north to -500 as the boundary, west and south on both sides by the Ordovician limestone control, the northeast can be down The depth of the stratigraphic course is gradually changing from north east to south east, and even east to west. Its shape resembles a dustpan with a northerly dip and a dip angle of 9 ° 30 to 27 ° 40.
