喜人公司磷矿通风系统及排水系统施工

Construction of ventilation system and drainage system in Xiren phosphorus mine

为了解决矿山开采设计方案与企业实际现状相差较大的问题,根据喜人磷矿多年的现场施工研究和实践经验,通风系统变更为中央对角式通风方式,从主井进风,1#斜坡道与2#斜坡道出风,不另设风井.通过变更方案,节约了掘进风井费用,降低了风阻,减少了通风费用.将排水系统由分级排水方案变更为一级排水方案并加大水仓容积.更改后的排水方案不仅减少了-10M水平水仓及泵房的投入,而且减少了-10M水平、+40M水平两级泵房的人员管理成本,虽增加水仓容积加大了投资,但实现了错峰低谷用电排水,降低了排水成本.

In order to eliminate the differences between mining design scheme and actual situation of the corporation, central-diagonal ventilation was adopted in ventilation system, according to the author＇s experience of construction in Xiren phosphorus mine. Air entered main shaft and came out from ramp No. 1 and ramp No. 2, without extra air shaft. By means of changing the plan, cost of driving wind well and ventilation was cut down. Besides, wind resistance was reduced. Multistage drainage was replaced by single-stage drainage plan. Additionally, the capacity of water sump and the storage time were increased. In the amended plan, investment for water sump and pump room on --10m level is canceled. Thus, the personnel management cost of the two pump rooms on --10m level and ＋40m level is cut down. Although the investment of water sump is increased for the sake of increasing capacity, off-peak power consumption in the depressed time is realized and drainage cost is reduced.
