摘要
金属矿山外部漏风量大,致使矿井有效风量率达不到国家规定标准,是中后期矿井普遍存在的问题,也是目前尚无有效方法解决的问题。本文作者通过对河北省内一些矿山的调查、测定和分析,提出一种解决矿井外部漏风的新途径,即利用矿井外部漏风做风源,解决矿井通风除尘问题,以达到变害为利的目的。
It is commonly existing problem in old metal mines that available airflow rate can not reach ventilation standard, which is caused by the leakage of large quantitiesair, so far of there is no effect method to solve it. We put forward a new way to solve this problem based on our research, test and analysis work in mines of Hebei Province, i. e. to use exteranl leakage air as an air-flow source in order to solve the problem of ventilation and dust-laying, therefore the disadvantage will be transformed into the advantage.
