我队在仁虎山沟矿区进行坑探施工时,由于空压机厂房位置选择不当,采用2台75马力移动式空压机井联送风,空压机厂房距离152坑约800公尺,距离292坑约950公尺,长期只带动2台-OM-506凿岩机,因此,凿岩效率虽高,但动力费超支严重,经济上不合理.当时虽经过多次检查,但未找出原因,及时得到合理解决.后来采用试验测定的方法,通过多次的试验研究后,才找出了影响空压机效率低、风压低风量不足的原因,从而采取相应的措施,基本上解决了上述问题.现将我们试验的的情况及其改进措施介绍如下:一、试验情况及影响风压风量的原因1、开动2台75马力空压机带动2台OM-506凿岩机的风压情况:152坑进行凿岩时正常终压为5.5Kg/Cm~2,292坑正常格压为5kg/Cm~2;停止一台凿岩机时,152坑风压为6.2kg/Cm~2,292坑风压为6Kg/Cm~2.
When our team conducted pit exploration at the Renhushangou mining area, due to improper selection of air compressor plant location, two 75-horsepower mobile air compressor wells were used to send air, and the air compressor plant was located at a distance of 152 pits of about 800 meters. The 290 pit is about 950 meters long and only two sets of OM-506 rock drills have been driven in the long term. Therefore, although the rock drilling efficiency is high, the overdraft of the power costs is serious and the economy is unreasonable. At that time, although several inspections were conducted, no reason was found. A reasonable solution was obtained in a timely manner. Later, through trial and error tests, after several trials and studies, the reasons for the low efficiency and low wind pressure of the air compressor were found, and corresponding measures were taken to basically solve the above problems. The current situation of our experiment and its improvement measures are described as follows: 1. Test conditions and reasons affecting wind pressure air volume 1. Start the pressure condition of 2 sets of 75 horsepower air compressors to drive 2 OM-506 rock drills: 152 pits The normal final pressure during rock drilling is 5.5Kg/Cm~2,292 and the normal grid pressure is 5kg/Cm~2; when a rock drill is stopped, the wind pressure at 152 pit is 6.2kg/Cm~2,292 and the wind pressure at the pit is 6Kg/Cm~ 2.
