摘　　要：大淑村勘查区位于峰峰矿区北部,太行山台背斜之东翼南段的鼓山背斜之东,含煤地层为石炭系本溪组、太原组和二叠系山西组,煤系地层总厚度约200m左右。共含煤16〜22层,总厚度15m左右,含煤系数7%左右。区内主要可采煤层2、4、6号煤层,煤变质程度很高,煤阶以无烟煤为主。煤层气含量在10〜15 m^3/t以上。该区为构造煤,储层渗透性较差。根据区块地质条件优选出2处参数井井位,并指出了后期勘探目标区。The Dashucun exploration area is situated in the northern Fengfeng mining area,to the east of Gushan anticline of Taihangshan anteclise east limb southern sector.Coal-bearing strata belong to Carboniferous Benxi and Taiyuan formations,Permian Shanxi Formation,total thickness of coal measures strata about 200m.Number of coal seams have 16〜22,total thickness about 15m with coal-bearing coefficient about 7%.Main mineable coal seams in the area have coal Nos.2,4 and 6;coal seams have very high degree of metamorphism,coal rank mainly anthracite.CBM content is 10〜15 m^3/t above.Coal in the area is tectonoclastic coal,permeability of coal reservoir rather poor.According to block geological condition has optimized 2 parametric well sites,and pointed out later period exploration target areas.
