用地下方法开采煤层的战略,归根结底可归结为:确定以采矿工作安全要求为一方,与劳动生产率为另一方之间的最佳配合问题。在危险程度不高和保护工人生命和健康的安全措施方法相当简单时,能提高劳动生产率。随着危险程度的增大和为创造安全和有利的条件所采取的措施复杂比,则安全要求和劳动生产率的要求相矛盾的局面就会出现,并且当煤层用现代方法开采变得不合理时,这些矛盾可能达到尖锐化。在这种情况下,从国民经济的观点出发,确定出人们可以接受的,对安全技术的最高要求和对劳 The strategy of using subterranean methods to mine coal seams can, in the final analysis, be attributed to the identification of the best fit between mining safety requirements and labor productivity as the other. Labor productivity can be increased when security approaches that are less dangerous and that protect the lives and health of workers are relatively simple. As the degree of danger increases and the complexity of the measures taken to create safe and favorable conditions arises, the conflicting requirements of safety requirements and labor productivity arise, and as coal seams become less rational with modern methods of mining, These contradictions may be sharpened. In this case, from the perspective of the national economy, we set out the most acceptable and safest technical requirements for labor
