河北省原煤生产在全国占有一定位置,近几年不断扩大矿井的生产能力,原煤产量逐年提高。但一些矿井的掘进速度与回采不相适应,采掘比例关系仍处于失调状态,迅速扭转这种局面是我省煤炭工业发展中的一个重要问题。怎样把掘进速度搞上去?根据我省目前的具体情况,要着重抓好煤巷掘进机的使用并逐步扩大使用范围,迅速提高煤巷的单进水平。我们的目标是要在几年之内,凡有条件使用掘进机的回采巷道,力争大部分使用上掘进机。我省现有掘进机24台,其中国产的2
Coal production in Hebei Province occupies a certain position in the country, in recent years continue to expand the production capacity of coal mines, raw coal production increased year by year. However, the speed of some mines is not compatible with the recovery and the proportion of mining is still in a state of imbalance. It is an important issue in the development of coal industry in our province to quickly reverse this situation. According to the current situation in our province, we should focus on the use of coal heading machine and gradually expand the scope of use, and quickly improve the single entry level of the coal lane. Our goal is to be within a few years, where conditions permit the use of roadheader mining roadway, and strive to use most of the roadheader. There are 24 tunnel boring machines in our province, of which 2 are domestically produced
