日前在山西省科委主持的科技成果鉴定会上,由潞安矿业(集团)公司王庄煤矿研究的“综放提高采出率”成果顺利通过鉴定。 “综放提高采出率研究”提出了提高放出率是综放开采研究的核心,综放开采煤炭损失主要包括放煤损失、上下端头损失、初末采损失和护巷煤柱损失。课题运用顶煤弱化理论、三段式压力理论和围岩大结构稳定理论,开展了以下三个阶段的综采放出率研究: 第一阶段为提高顶煤放出率的研究(1988～1993年)。其中包括:预注水顶煤弱化研究、
A few days ago in Shanxi Province Science and Technology Commission presided over the scientific and technological achievements appraisal meeting by the Luan Mining (Group) Company Wangzhuang coal mine “fully mechanized caving increased production rate ” The results passed the appraisal. “Research on raising rate of fully mechanized coal caving ” raised the rate of release is the core of the study of fully mechanized caving mining, coal mining losses mainly include coal caving loss, upper and lower tip loss, loss of initial and final mining and pillar loss . The subject uses the top coal weakening theory, the three-stage pressure theory and the stability theory of surrounding rock large structure to carry out the following three stages of the study on the rate of fully mechanized mining: The first phase is to study the study of increasing the rate of top coal (1988-1993) . Including: Pre-injection top coal weakened research,
