该矿位于北京西山东南边缘,与同华北平原接壤的丘陵地带相邻,西北部为中低山地。丘陵地带多U形谷,沟谷大部垂直地层走向和斜交地层走向。 构造部位为北岭向斜南翼。在井田东部发育次一阶构造——长沟峪向斜和老窑沟背斜;井田西部为单斜构造。区内断层有西安正断层,罗圈椅逆断层及洞儿沟平推断层。 The mine is located in the southeastern margin of Beijing Xishan, adjacent to the hilly areas bordering on the North China Plain, and low-lying mountains in the northwest. U-shaped valley in the hilly valley, most of the valley vertical strata and bias stratigraphic strike. Tectonic site for the North Ridge south wing. In the eastern part of Wellfield, there are sub-first-order structures - Changgouyu syncline and Laoyao ditch anticline; the western part of the minefield has a monoclinic structure. Faults in the area are Xi’an Normal Fault, Luozhaizi thrust fault and Dongergou thrust fault.
