霍尔辛赫煤矿南二采区开采设计论文毕设论文.docVIP

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 ABSTRACT The design for the Second South Huo er xin he coal mining area design, the design of pre-production capacity of 2.4Mt / a, or as a late 3Mt / a, length of service for 9.22a. Mine is only on the 3rd coal mining. Mining area from east to west on average 5.88km, north-south width 2.66km, area 9.88k ㎡. The total reserves of industrial 66577kt, recoverable reserves 38731kt. Mining area rich in coal reserves, the exploitation of the average thickness of 5.8m (net coal thickness of 5.5m), coal quality is better, development of stable, single-layer thin tonstein (0.2 ~ 0.3m), a relatively simple structure, flat seam occurrence, the general inclination in the 0 ° ~ 5 ° or so. Seam roof and floor rocks are mostly shale, mudstone, siltstone, fine sandstone and so on. Mining villages in the region as a result of the ground covered, the impact of underground mining methods is a major factor in selection. In order to maximize resource utilization, as well as the geological conditions of coal by other factors, take into account the above factors, the multi-program comparison, we have decided to adopt the area of the conventional fully mechanized caving and strip mining coal mining jumped, all face integrated mechanized mining. A total of 21 mining area of conventional top-coal caving face and jumped six bands of fully mechanized caving coal surface mining.
