城郊煤矿2.4Mta新井设计【专题浅析锚网索钢带耦合支护技术的研究及运用】.doc

1、摘 要本设计包括三个部分：一般部分、专题部分和翻译部分。一般部分为城郊煤矿2.4Mt/a新井设计。城郊煤矿位于河南省永城市，井田南北长约6.5km，东西宽约6.1km，勘探面积约35.3km2。此井田中只有1煤层厚7.13m，这层煤从厚度和赋存条件是可采煤层。井田工业储量为35935.52万t ，矿井可采储量23567.1923万t，矿井服务年限为70.1a。井田开拓采用立井两水平开拓，暗斜井延伸。采煤方法采用综合放顶煤采煤，工作面布置为带区式布置。大巷布置为皮带大巷运煤兼进风，轨道大巷回风兼辅助运输，。矿井通风方式为中央并列式,掘进头采用局扇通风。矿井总需风量为4730.4m3/min，通风

2、阻力容易时期为956.5Pa，困难时期为1617.5Pa。矿井巷道等积孔容易时期为3.08m2，困难时期为2.38m2。通过计算决定选用FBDCZ(B)-12-No28轴流式通风机，其能满足矿井对风量的要求。综上所述，城郊矿通风系统简单，合理，稳定，满足通风要求，抗灾能力强。专题部分题目是浅析锚网索钢带耦合支护技术及运用，主要是研究倾斜煤层深部开采时的支护方法。翻译部分主要内容为锚网索钢带耦合支护技术研究。英文题目为：Measuring pillar width in trona mines using a body wave based in-seam seismic technique关键

The Cheng Jiao minefield lies in the special area of Yong Cheng city, Henan province. Total area of the mine is

4、 35.3 km2. The boundary of the minefield runs 6.5 km on north south and 6.1 km on west east on average. There are one main seamsthe third layer with thickness of 7.13 meters. According to the thickness and deposit, this coal layer is able seams. The industrial storage of the mine field is 359.3552 m

5、illion ton, the reserves exploitable in the whole mine field is 235.671923 million ton，and its service life is 70.1 years, with only one working faces is used in the mine. Two standards development are used in the Mine shaft pioneering,with subinclined shaft extension.The Coal mining use a comprehen

6、sive top coal caving mining.The track roadway with the airflow into are mainly used to transported the coal while the belt roadway are used to the auxiliary transport with the return of airflow.The method of whole mine ventilation is central juxtapose ventilation system.The ventilation of the dead-e

7、nd working places is the application of the auxiliary ventilation by the auxiliary fans. The total amount of wind required is 4730.4m3/min, and the ventilation resistance 956.5Pa at easy period while difficult period of 1617.5 Pa. The equivalent orifice is 3.08 m2 when easily period whlie difficult

8、period is 2.38m2.So I choose the FBDCZ(B)-12-No28 with the axial-flow as the main fan which can meet the need of the whole airflow of the requirement.In summary, the suburban mine ventilation system is simple, reasonable, stable and meet the ventilation requirements of fighting ability.Special part

9、is Analysis of anchor cable steel belt coupling supporting technology research and Application, mainly on inclined coal seam in deep mining support method.The translation part is measuring pillar width in trona mines using a body wave based in-seam seismic technique .Key words: Cheng Jiao mine; the
