珲春矿业集团公司八连城煤矿属于薄煤层开采,井下综采工作面配备有辽远煤机厂生产的MG2×70/330-BWD型采煤机,采用交流变频调速技术实现牵引速度无级调速。为使机身电控箱简化,缩短机身长度,提高薄煤层采煤机的适用性,变频部分安装在顺槽内。采煤机均采用MCP3×50+1×10+3×6型和MCP3×50+1×10+7 × 4型两种规格多芯采煤机专用电缆供电,组合开关控制,安装在下顺槽,距离回采工作面平均500 m左右;采面布置长度在200m以下,
The coal mine of Hualien Mining Group Co., Ltd. belongs to thin coal seam mining and the fully mechanized coal mining face is equipped with MG2 × 70/330-BWD coal shearer manufactured by Liaoyuan Coal Mining Machinery Factory. The AC variable frequency speed regulation technology is adopted to realize the traction speed stepless speed regulation . In order to simplify the fuselage electric control box, shorten the fuselage length, improve the applicability of the thin coal seam shearer, frequency conversion part installed in the cistern. Shearer adopt MCP3 × 50 + 1 × 10 + 3 × 6 type and MCP3 × 50 + 1 × 10 +7 × 4 two types of multi-core shearer special cable power supply, combined switch control, installed in the next slot , An average distance of about 500 m from the mining face; face length less than 200m,
