霍尔辛赫煤矿南二采区开采设计.doc

摘要

本设计为霍尔辛赫煤矿南二采区设计，设计生产能力为前期2.4Mt/a，后期升之为3Mt/a，服务年限为9.22a。井田只开采3号煤层。采区平均东西长5.88km，南北宽2.66km，面积9.88k㎡。总的工业储量为66577kt，可采储量38731kt。采区煤层储量丰富，开采厚度平均5.8m（纯煤厚度5.5m），煤质较好，发育稳定，单层夹矸薄（0.2~0.3m），构造比较简单，煤层产状平缓，倾角一般在0°~5°左右。煤层顶底板岩层多为泥岩、砂质泥岩、粉砂岩、细砂岩等。由于采区内地面村庄密布，是影响井下开采方法选择的主要因素。为了尽量提高资源利用率，以及受煤层地质条件等其它因素影响，考虑以上诸多因素，经多方案比较后，决定本采区内采用常规综放和条带跳采采煤法开采，工作面全部为综合机械化采煤。采区内共有21个常规综放工作面和6个条带跳采综放采煤面。
关键词：采区设计常规综放条带跳采综合机械化
