The new type hydraulic prop reduces the accidents due to the seal leaking by using seal-compensation and seal-swelling, and reduces seal change times and maintenance times. 新型液压支柱采用密封补偿和密封胀紧等密封方式，可减少因密封泄漏而造成的冒顶等事故隐患，减少密封更换次数及维修次数。
Hidden failures can be early found and maintenance cost can be cut through the monitoring of machine status and the use of failure diagnostic technique. 通过对机器状态的监测及故障诊断技术的应用，可以及早地发现事故隐患，减少维修成本。
