| 摘 要： | 新疆拜城县梅斯布拉克煤矿煤炭资源丰富,煤种以25号焦煤为主,井田内梅斯布拉克河由北向南从中部穿过,若预留河床煤柱则要减少焦煤资源量800万t,不留则会导致开采技术条件复杂化,根据当地水文地质条件及相关规范,计算导水列隙带高度为190.23m,在煤炭正常开采时,其下部272.77m是安全的,预计可解放河订煤柱500万t.

| Abstract: | Mais Bulak Coalmine in Bay County, Xinjiang Region has abundant coal resources; coal rank is mainly short supplying high quality metallurgical used No.25 coking coal. Mais Bulak River flows from north to south pass through the minefield in the middle. If the coal pillar under the channel is needed, 8 million tons of coking coal resource will be lost, if no safety coal pillar left, the mining technical condition will be complicated. Thus the problem is worthwhile to be discussed thoroughly, to save coal resources and get enormous economic benefit. |
