| 摘 要： | 随着国内大中型煤矿的发展,在中厚煤层开采过程中,由于各个煤矿的地质条件不同,特别是煤质硬度和工作面压力的关系,极易造成大块煤炭的脱落并形成1 m见方的不规则炭块,这样不仅造成输送机无法正常运输,并严重影响煤矿的正常生产和效益,通过对井下现场的实际考察,设计出了适合井下工作面的大块炭破碎装置。该装置采用液压系统定位,锤头油压冲击破碎的方法将特大块炭破碎成中型炭块,以便于输送机的正常运输。通过井下试验证明,该装置使用效果良好。

| Abstract: | With the development of domestic large and medium-sized coal mine,due to the geological conditions of various coal mine is diverse,especially the hardness is closely related to the working pressure,the falling of the large carbon take place now and then in mining process and create irregular cinderblocks of about one square meter.It not only make the scraper conveyor doesn't work,but also influence the production efficiency seriously.Through the investigation on the actual situation,we designed the crushing... |
