合理开拓部署是多快好省地发展煤炭生产的一项重要措施,它对实现机械化,降低掘进率,保持采掘正常接续,提高矿井生产能力和单采水平都关系重大。 打通一矿系近水平近距煤层,于70年7月投产。过去主要由于林彪和“四人帮”反革命修正主义路线的干扰破坏,使矿井投产七年尚未达到设计能力。同时,在开采过程中,由于开拓部署和巷道布置不够合理,矿山压力大,造成巷道破坏,地面向井下渗水,使巷道积水、淹没工作面,以及运输环节多,管理分散等,严重影响井下生产。
Proper exploration and deployment is an important measure to develop coal production in a more efficient and economical manner. It is of great importance to mechanization, lowering of the rate of excavation, keeping normal mining continuity and improving mine productivity and single-production level. Close to a mine near the horizontal coal seam, put into operation in July 70. In the past, due to the interference and destruction caused by the counterrevolutionary revisionist line of Lin Biao and the “gang of four,” the design of the mine has not yet reached its design capacity for seven years. In the meantime, during the mining process, due to the unreasonable layout and layout of the roadway, the pressure of the mine, the destruction of the roadway, the water seepage down the ground, the waterlogging of the roadway, the submergence of the work surface, the multi-transportation links and the scattered management, produce.
