煤巷掘进机由于掘进速度快、工效高、劳动强度低、巷道规整和安全等优点,因此日益为国内外煤矿掘进所采用。自第一台掘进机产生迄今,三十多年来,经过不断的改革、提高、发展,在许多国家已生产出不同性能、规格的各类掘进机数十种。其可切割矿物硬度、功率、可靠性、机体重量、切割断面等均有较大的提高,机器的性能也日益完善。并相应的发展了支护、灭尘、转载运输等配套设备,以利于综合作业,提高技术
Due to the advantages of fast heading speed, high working efficiency, low labor intensity, regular and safe roadway, coal tunnel boring machine is increasingly used in domestic and international coal tunneling. Since the first tunnel boring machine was produced, over the past 30 years or so, after continuous reform, improvement and development, dozens of various roadheaders have been produced in many countries with different performance and specifications. Its cutting mineral hardness, power, reliability, body weight, cutting cross-section, etc. have greatly improved, the performance of the machine is also increasingly improved. And the corresponding development of support, dust, reprint transport and other ancillary equipment, in order to facilitate comprehensive operations and improve technology
