摘要
榆家梁1#矿井井田位于陕西省榆林市神木县东北部,行政区划隶属于神木县店塔乡管辖。井田南距神木县城31km,榆林130km,***410km,西安850km,北距内蒙古东胜市185km,包头市300km,东距山西阳方口180km。海拔高度一般在1100-1300m。本区属中温带大陆性气候,基本特征为冬季长而寒冷,夏季炎热干旱,春季风沙频繁,昼夜温差悬殊,水文地质条件简单,地下水补给贫乏,岩层富水性弱,无较大的地表水系。
本设计针对井田5-2煤层的开采进行设计,5-2煤层地质储量为27965万吨,设计可采储量为207,倾角1~2°,平均煤厚6.29m。井田构造简单,***含量低,开采技术条件较好,有利于综合机械化开采。结合资料对本矿的开拓提出两个方案进行比较,最后得出采用斜井开拓方式较合理,采用双斜井开拓。设一个开采水平,初期开凿两条斜井和一条立井,其中一条主斜井,一条副斜井和一号回风立井。井下通风方式为抽出式,初期采用中央并列式通风系统,后期在井田南部布置一个立井,作为二号回风立井,形成混合式通风。井田共布置五个盘区,回采5-2煤层。年产量为2.4Mt/a,服务年限62a。采用了综采后退式放顶煤一次采全高全部垮落倾斜长壁采煤法。辅助运输采用无轨胶轮车运输,实现从地面到井下的连续运输,从而实现系统简单化。

ABSTRACT
Yujialiang 1# coal mine is located in the Yulin city in Shanxi Province,Shenmu northeast, administrative divisions under the jurisdiction of the rural Shenmu Dianta. Ida north of Shenmu county 31km, Yulin 130km, Yan'an 410km, Xi'an 850km, south of city in Inner Mongolia 185km, Baotou City, 300km, east Shanxi Yang Fang mouth 180km. Altitude is generally 1100-1300m. The area belongs to the temperate continental climate, the basic characteristics of long, cold winter, hot summer droughts, frequent sandstorms in spring, day and night temperature and the poor, hydrogeological conditions are simpldwater recharge is meager, water yield property of weak, climate drought little rain, no large surface water.
The design for the Ida 5-2 mining design of 5-2seam, geological reserves 279650000 tons, design recoverable reserves of 207148400 tons, angle 1 ~ 2 °, the average coal thickness . Ida has the advantages of simple structure, low ga
