我国统配煤矿煤层厚度在1.5～3m内的工作而产量约占全部产量的40％以上。因此,研制一种主要适用于上述采高范围内的较为先进的、中等功率的采煤机很有必要。煤炭科学院上海所设计、无锡采煤机械厂制造的MG150—W(无链基本)型采煤机,是1983年煤炭部下达的重点科研项目。该机于1986年造出样机,出厂试验合格后,又经过煤炭科学院上海采煤机质量监督检测中心切
China’s coal mine seam thickness in the 1.5 ~ 3m within the work and the output of about 40% of the total output. Therefore, it is necessary to develop a more advanced, medium-power shearer that is mainly suitable for the above-mentioned mining heights. The MG150-W (chainless) shearer, designed by Shanghai Academy of Coal Science and Designated by Wuxi Coal Mining Machinery Factory, is a key scientific research project issued by the Ministry of Coal Industry in 1983. The aircraft in 1986 to create a prototype, after passing the factory test, and after the Coal Mining Academy of Shanghai Shearer Quality Supervision and Testing Center cut
