前言 劳动保护研究的范围很广,包括劳动保护标准,劳动安全技术和装置、工业通风、有毒物质、工业噪音、个体防护、电子技术在安全防护中的应用等。我们这次的调研课题主要是薄煤层煤矿井下工人的个体防护情况。 从煤炭的储量和产量的构成来看,薄煤层开采的比重必将越来越大。在我省,仅徐州矿务局的薄煤层储量就占42.3％,目前可开采的占25％。因此,调查薄煤层开采的劳动防护情况,研制新的防护用品,具有一定的现实意义。薄煤层作业空间小,弯腰弓背匍匐爬行,主要以跪、坐姿势进行作业。地
Preface Labor protection studies cover a wide range of topics including labor protection standards, labor safety technologies and devices, industrial ventilation, toxic substances, industrial noise, individual protection and the application of electronic technology in safety protection. Our main research topic this time is the individual protection of workers in thin seam coal mines. From the composition of coal reserves and production point of view, the proportion of thin coal mining will certainly be more and more. In our province, only the Xuzhou Bureau of Mines reserves 42.3% of the total coal reserves, the current recoverable 25%. Therefore, the investigation of thin coal seam mining labor protection situation, the development of new protective equipment, has some practical significance. Thin seam work space is small, bent bow back creeping, mainly to kneel, sit posture for homework. Ground
