摘 要
本設(shè)計以華亭煤礦5號煤層為開采煤層。5#煤層地質(zhì)條件較為簡單，煤層傾角6-8度，平均煤厚39.2m，礦井設(shè)計資源量556.6Mt，設(shè)計可采儲量358.5Mt，設(shè)計生產(chǎn)能力3.52Mt/a，服務(wù)年限79a。
本礦井采用立井開拓，設(shè)置主立井，副立井，回風(fēng)立井。采區(qū)劃分，條帶式開采，采用傾斜長壁分層綜采低位放頂煤法。本設(shè)計是以華亭煤礦的地質(zhì)資料為基礎(chǔ)，在贠老師的精心指導(dǎo)下，嚴(yán)格按《煤礦安全規(guī)程》、《煤礦設(shè)計規(guī)范》要求設(shè)計。本設(shè)計以理論聯(lián)系實際，重點(diǎn)針對該礦井的概述及礦井地質(zhì)、井田境界及儲量、井型服務(wù)年限、井田開拓、采煤方法、井下運(yùn)輸、提升方式、通風(fēng)與安全、排水等方面展開的，對同類礦山開采具有一定指導(dǎo)意義。
關(guān)鍵詞：采煤方法、立井開拓、綜采放頂煤、分層開采、運(yùn)輸、通風(fēng)、環(huán)境保護(hù)
Abstract
The paper is designed on the basis of 5# coal seam on Huating coal mine.The geological condition of 5#coal seam is simple and its dip angle coal is 6 to 8 degree. Besides the average thickness of 5#coal seam is nearly 39.2m. The designed mine resource is 445 Mt and recoverable reserves is 306.12 Mt.The coal seam of design production capacity is 3.4Mt/a and the length of service is 89 years.
This mine uses shaft development way, sets the main shaft, auxiliary shaft and air shaft. Disk partition, strip mining, using full-mechanized caving mining method. The design is based on Huating coal mine geological data, the instructor under the careful guidance by teacher Cao, in strict accordance with the" coal mine safety regulations"," standard" requirements of the design of coal mine design. This design to link theory with practice, focus on the mine survey and mine geology, Ida state and reserves, well service life, Ida forge, mining method, underground transport, lifting, safety and ventilation, drainage and other aspects, for similar mining has certain guiding significance.
Key words: vertical shaft development、full-mechanized caving mining、layer mining、transportation、ventilation、environmental protection
