| 中文摘要:钻孔水力采矿由于安全系数高、工程效益和生态环境保护好等优点在国外一直被研究和使用。我国相关的科研院所也正在开展研究。本文在分析研究国外钻孔水力开采装置的基础上，研制了具有自主知识产权的棘爪机构伸缩式钻孔水力开采装置。该装置利用机械式伸缩水枪的方式扩大水力开采矿层的范围，创新性地采用棘爪机构固定水枪的伸出角度，从而提高单孔开采量，降低开采成本。初步野外实验结果表明，该装置结构设计合理、工作可靠性高，可有效进行开采，达到了预期的目标。 |

| Abstract:Hydraulic borehole mining has been researched and used abroad due to the advantages of high safety factor, engineering benefit and good ecological environment protection. Some related research institutes in China are also carrying out this research. On the basis of analyzing the hydraulic borehole mining equipment in foreign countries, pawl telescopic mining equipment with independent intellectual property rights is developed. In order to increase the single hole mining volume and reduce the mining cost of this mining equipment, not only mechanical telescopic gun, but also pawl mechanism are innovatively used to secure the protrusion angle of the water gun to expand the area of hydraulic mining seam. The preliminary field experiments show that this pawl telescopic mining equipment has reasonable structure design with high work reliability, the expected target is achieved by the effectively mining. |
