国内外实验室试验证明,高压水射流能够切割或破碎煤体和岩石,但作为一项新技术用于煤炭生产,目前国际上还处于试验阶段。 在煤炭生产中,采掘失调是多年来存在的老大难问题。为了提高掘进速度,各国都在研制机械切割的掘进机,或者仍采用打眼放炮的方法爆破掘进。前者机械设备体积大、吨位重、造价昂贵;后者工人劳动条件差、生产事故多。因此急需寻求一种快速安全、经济轻便的掘进新工艺。国内外采掘工业都对高压水射流技术寄予很大希望。 我国煤炭科学院副院长汤德全教授指
Domestic and international laboratory tests show that high-pressure water jet can cut or break coal and rock, but as a new technology for coal production, it is still in the experimental stage in the world. In coal production, the imbalance in mining has been a chronic problem for many years. In order to improve the speed of driving, all countries are developing mechanical cutting machine boring machine, or still use the method of blasting shot blasting. The former machinery and equipment bulky, heavy tonnage, costly; the latter poor working conditions, production and more accidents. Therefore, it is urgent to seek a fast, safe and economical light driving new technology. The extractive industries at home and abroad place great hope on high-pressure water jet technology.
