50多年前的华北,是抗日战争的前线阵地,也是煤矿企业和煤矿工人最集中的地区。1937年芦沟桥事变后短短半年,华北各地煤矿几乎全部沦入敌手。广大煤矿工人在中国共产党的领导和号召下,纷纷组织起来,建立抗日游击武装,奔赴抗日前线,与八路军、新四军和其它抗日武装汇合,成为开辟抗日根据地和坚持敌后游击战争的重要力量。 North China more than 50 years ago was the front line of the anti-Japanese war and the region where coal mines and coal miners are most concentrated. In 1937, just six months after the Lugouqiao Incident, coal mines in almost all parts of North China fell into rivalries. Under the leadership and call of the Chinese Communist Party, the vast number of coal miners have organized themselves to establish anti-Japanese guerrillas, went to the frontlines of the anti-Japanese war, merged with the Eighth Route Army, the New Fourth Army and other anti-Japanese militias and become important forces for opening up the anti-Japanese base areas and upholding the enemy-guerrilla warfare.
