河北省县以上的地方煤矿有100多个,原煤产量几年来一直在1300万吨以上。这对发展本省的地方工业、农业和保障人民生活用煤做出了很大的贡献。 随着地方煤矿不断地进行技术改造,近年来,矿井生产技术面貌发生了较大变化。开拓布局、巷道布置日趋合理,技术装备、机械化水平不断提高,安全生产状况得到改善,高落式、残柱式、落垛式等落后采煤法进一步改革,有力地促进了煤炭生产稳步发展。
There are more than 100 local coal mines above the county level in Hebei Province, and the output of raw coal has been above 13 million tons in recent years. This has greatly contributed to the development of local industries, agriculture and coal for people’s livelihood in the province. As the local coal mines continue to carry out technological transformation, in recent years, great changes have taken place in the technical aspects of mine production technology. Open layout, roadway layout is becoming more reasonable, technical equipment, mechanization level continues to improve, safety conditions have improved, high-style, residual column, falling pile and other backward mining method of further reform, effectively promoted the steady development of coal production.
