瓦斯抽放对矿井“三量”可采期的优化研究

Optimization Research of Gas Drainage Quantity on Minable Period of“Three Quantities”

矿井"三量"即指开拓煤量、准备煤量及回采煤量。为了研究瓦斯抽放对矿井"三量"可采期的优化作用,以鹤壁矿区所属矿井为实例,在对目前生产接替中存在的主要问题分析的基础上,就瓦斯预抽对"三量"可采期的影响进行专门研究,主要通过实施瓦斯的综合抽放和编制合理的采掘接替计划来保证回采工作面的安全生产,最终制定出合理的适合鹤壁矿区生产实际的"三量"关系。

'Three Quantities'of mine are the developed coal reserve, prepared coal reserve, visible coal reserve. In order to study the 'Three Quantities' minable period optimization effect of gas drainage,take the coal mine of Hebi mining area for example, based on the analysis of main problem in production relay at present, a specialized study of 'Three Quantities' under the influence of gas drainage was conducted, mainly by means of the implementation of comprehensive gas drainage and the formulation of reasonable mining succession plan to ensure the production safety of the mining working face. Lastly, ‘Three Quantities' fit for the production fact of Hebi mine are constituted by general analysis.
