煤矿工业建设,既需要较多的投资,又需要较长的时间,一个中型矿井由探勘至达到设计产量,一般说要六年到八年的时间,要二千一亿资金,另一方面我国原有矿井,由于在旧中国长期受帝国主义及官僚资本的掠夺开采,形成掘进落后于回采的不合理现象;解放后虽曾加以改进,但由于缺乏正确处理掘进工作的经验和理论,这一工作仍停留在摸索阶段.有不少矿井还没有完全彻底改变旧有的面貌,不能很好进行有计划的生产,对完成国家任务的保证上,造成很多困难;因此加快井巷的开拓工作、经济合理的使用原材料,缩短新并建设时间,改造旧有矿井,以适应国家大规模建设的需要,是煤矿工作者担负的艰巨而光荣的任务.
The construction of coal mining industry requires more investment and requires a longer period of time. A medium-sized mine has to be surveyed until it reaches design output. It generally takes six to eight years, and it requires funds of 201 billion yuan. On the other hand, China The original mine, because of long-term exploitation by imperialists and bureaucratic capital in old China, formed an irrational phenomenon that the digging and lagging behind came back. Although it was improved after liberation, due to the lack of experience and theory in correctly handling the excavation work, this Work still remains at the stage of exploration. Many mines have not yet completely completely changed the face of the old, are not able to carry out planned production well, and have caused many difficulties in ensuring the completion of the national tasks; It is an arduous and glorious task for coal mine workers to use raw materials economically and rationally, shorten new construction time, and rebuild old mines to meet the needs of large-scale national construction.
