王石凹煤矿位于陕西渭北石炭二叠纪煤田西部铜川矿区的中央。东一上山采区是该矿的首采区,同期开采三层煤:山西组下部的3号煤、太原组上部的5号煤和底部的10号煤(图1)。至今已开采了二十多年,已掘进不同层位的各类巷道30余万米。采空的工作面54个。三个煤层中各种构造的空间变化和组合关系已清晰地展示出来。这对剖析
Wang Shek-wah coal mine is located in Shaanxi Weibei Carboniferous Permian coalfield west of the middle of the Tongchuan mining area. The Dongshangshan mining area is the first mining area of the mine. Three layers of coal are mined in the same period: coal No. 3 in the lower part of the Shanxi Formation, coal No. 5 in the upper part of the Taiyuan Formation and coal No.10 in the bottom (Figure 1). So far, it has been mined for more than 20 years and has dug more than 300,000 meters of various types of tunnels in different layers. Mined the face 54. The spatial variation and combination of various structures in the three coal seams have been clearly demonstrated. This analysis
