这一研究成果是由美国国家煤炭局的罗伯特·A·傑考斯基,石油、采矿技术顾问R.C.傑勒斯和烟煤研究有限公司的J.F.柯里奈特共同提出的,可以直接用于长壁采煤工作现场。 傑考斯基指出,虽然长壁采煤有很多优点,但它本身现存的严重问题是不能使煤尘浓度保持在联邦政府标准每立方米2毫克以下。如果这一问题不能很好解决,长壁采煤法的高产和其它优越性将很难得到发挥。 他们提出一篇处理长壁采煤法中煤尘问题的论文,题为“长壁采煤法控尘设计须知”。共包括以下七点:
This research result was jointly proposed by Robert A. Jaykowski, National Coal Board of the United States, RC Jerrys, oil and mining technology consultant, and JF Curienet, a research institute of Bituminous Coal, which can be directly applied to longwall mining Coal work site. Jaykowski pointed out that although there are many advantages of longwall coal mining, its own serious existing problem is that coal dust concentrations should not be kept below 2 milligrams per cubic meter of federal government standards. If this problem can not be solved well, the high yield and other advantages of the longwall mining method will be hard to come by. They presented a paper dealing with the issue of coal dust in longwall coal mining, entitled “Design Guidelines for Controlled Dusting in Longwall Mining”. The total includes the following seven points:
