我国煤矿坑道钻探装备技术进展与展望

Advances and outlook of coal mine tunnel drilling equipment and technology

摘要:

煤矿坑道钻探装备技术在发展过程中受到诸多不利条件的限制，导致新技术发展滞后，随着我国煤矿大力推进智能化建设，给煤矿坑道钻探装备技术带来了革命性的发展机遇。通过分析国外坑道钻探装备的技术特点和发展状况，以及国内坑道钻探装备技术的3个阶段发展，包括初级阶段的分体式钻机与稳定组合钻具轨迹控制方法，蓬勃发展阶段的履带式钻机、定向钻进装备技术及松软煤层钻进技术，新发展阶段的自动化和智能化装备技术，提出了今后我国煤矿智能化发展阶段钻探装备技术需要解决的关键问题，为推进钻探装备技术智能化水平的提高提供支撑。

Abstract:

Coal mine tunnel drilling equipment and technology are restricted by many unfavorable conditions in the process of development， which leads to the lag of new technology development. The promotion of intelligence in China’s coal mines brings a revolutionary opportunity for the development of coal mine tunnel drilling equipment and technology. The foreign technical characteristics and development of drilling equipment are analyzed. At the same time， the paper also analyzes the three development stages of domestic tunnel drilling equipment and technology： the initial stage of the split type drill rig and the trajectory control method with the stable combined drilling tools； the vigorous development stage of the crawler drill rig， the directional drilling equipment and technology， and the soft coal seam drilling technology； the new development stage of the automatic and intelligent equipment and technology. The key problems are put forward with drilling equipment and technology in the intellectualized development stage of China’s coal mines in the future， which provides support for improving the intellectualized level of drilling equipment and technology.
