1、摘 要 本设计主题是为同煤集团四老沟矿井14#煤层设计的。大同四老沟煤矿位于大同西南方向25公里处,其详细的地理坐标为东径11256001130332,北纬39564340 0153。四老沟煤矿北部与同家梁矿相邻,其东北部余白洞煤矿相邻,其西北部与马脊粱矿和燕子山矿相邻,并且南部与雁崖井田相邻,西南部与杏儿沟矿相邻,东南部与马口井田相邻。四老沟十四号煤层的地质条件相对来说比较简单,只是有几条小断层,根据煤层实际情况,小断层对我们的开采影响不大,但是我们还是在这些小断层周边留设了保护煤柱,而且在设计开拓巷道的时候尽最大努力避开这些小断层影响。其中一条断层还可以作为带区边界。四老沟矿距离大同较近,
2、大同周边铁路四通八达,运输十分便利,而且井田内有公路贯穿,每日有客车来往,所以交通也很方便。 四老沟矿每年工作日为276 天(考虑国家最新规程,以及实际情况,实际生产工作日为300 天),工作制度为“三八”制,每日出煤班数为两班,每班工作8 小时。安全技术措施包括井下瓦斯煤层爆炸预防、水灾预防、火灾预防等措施。关键词:基本资料;矿井开拓;采煤工艺ABSTRACTThis design theme is designed for coal seam No. 14 of Silaogou Coal Mine. Datong Silagou coal mine is located 25 kilom
3、eters southwest of Datong. Its detailed geographical coordinates are 112 56n00 113 0332 east diameter and 39 56 (43) 40 0153 north latitude. The northern part of Siraogou coal mine is adjacent to Tongjialiang mine, the northeast Yubaidong coal mine is adjacent to the northeast, the northwestern part
4、 of the coal mine is adjacent to the Majiiliang mine and the Yanzishan mine, and the south is adjacent to the Yanya mine field, and the southwestern part to the Xingergou mine. The southeast is adjacent to the Makou mine field. The geological conditions of the coal seam No. 14 in Silaogou are relati
5、vely simple, but there are only a few small faults. According to the actual situation of the coal seams, the small faults have little impact on our mining, but we have set up protection pillars around these small faults. And do your best to avoid the effects of these minor faults when designing road
6、ways. One of the faults can also serve as a mining boundary. Silaogou mine is close to Datong, the railway around Datong is accessible, transportation is very convenient, and the road runs through the mine field, and there are buses and buses to and from each day, so the traffic is also very conveni
7、ent. The working day of Silaogou Mine is 276 days per year (considering the latest national regulations and actual conditions, the actual production working day is 300 days, the working system is four or six system, the number of coal production shifts is 3 classes per day, the working hours of each
