煤层和煤质工作区含煤岩地层为侏罗系下统八道湾组上段(J1b3), 总厚166.20～204.29 m、平均176.79m。共含煤1～4层, 由下至上编号为C1、C2、C3、C4煤层, 煤层总厚度平均为6.14m, 其中C1煤层厚度1.34米, C2煤层厚度3.14米, C4煤层厚度0.82米为全区可采。C3煤层厚度0.84米为局部可采。工作区北部煤层出露地表, 煤层向南顷, 倾角平均5度左右。煤炭资源量约9200万吨广州翻译公司。
Coal bed and coal quality working area coal bearing stratum is Jurassic System lower series Badaowan form upper section (J1b3), total thickness is 166.20～204.29 m, average 176.79m. Totally there are 1～4 coal bearing beds, which are numbered as C1, C2, C3 and C4; average total coal bed thickness is 6.14m, in which thickness of coal bed C1 is 1.34 meters, thickness of coal bed C2 is 3.14 meter, thickness of coal bed C4 is 0.82 which are totally exploitable, thickness of coal bed C3 is 0.84 meter and is partially exploitable. Coal bed in the north of the working area is exposed out of ground surface, coal bed inclines southwards, average inclination angle is approximately 5 degree. Coal resources is approximately 92 million tons.
区内分布有华力西期的侵入岩, 主要为细晶花岗岩(γo42)。ZK0703在侏罗系下统八道湾组上段(J1b3)底部见侵入岩、ZK0005在侏罗系下统八道湾组中段(J1b2)见侵入岩。煤层位于侏罗系下统八道湾组上段(J1b3)中部, 侵入岩对煤层、煤质的影响较小。但工作区工作程度较低, 侵入岩与工作区构造的关系及对煤层、煤质的影响还需要进一步研究日语翻译。
Intrusion rocks of Hualixi phase are distributed in the area, and are mainly of aplite granite (γo42). ZK0703 is at the Jurassic System lower series Badaowan form upper section (J1b3), intrusion rock is seen at bottom, ZK0005 is at the Jurassic System lower series Badaowan form middle section (J1b2), intrusion rock is seen. Coal bed is at the Jurassic System lower series Badaowan form upper section (J1b3), middle section, effect of intrusion rock upon coal bed and coal quality is small. But working degree of the working area is low, further research is required for the relationship between intrusion rock and working area structure and effect upon coal bed and coal quality.
