本書是研究綜放開采頂煤與頂板活動規(guī)律的專著。作者抓住綜放開采采厚大、頂板活動空間大、頂煤體力學(xué)變形特征在圍巖活動規(guī)律與“支架-圍巖”相互作用關(guān)系中起關(guān)鍵作用的特點，深入研究了綜放開采頂煤運移規(guī)律。從綜放工作面頂板控制的角度，給出了綜放開采直接頂、基本頂?shù)男露x；從上位頂板對綜放支架有無作用力的角度提出了“有變形壓力巖層”與“無變形壓力巖層”。在此基礎(chǔ)上研究了綜放開采上位巖層形成“組合短懸臂梁-鉸接巖梁結(jié)構(gòu)”的機理，得出了綜放支架工作阻力下限值的計算公式及影響因素。將此理論應(yīng)用于淺埋煤層綜放開采中，得出了不同地質(zhì)條件下覆巖所成結(jié)構(gòu)與液壓支架工作阻力下限值的確定方法。ISBN 978-7-5020-5583-7

Executive Summary
This book is on studies of movement regularities of top coal and
roof in top coal caving mining. In top coal caving mining,
mining thickness and space for roof movement is large, and top coal deforms
under mechanics. These play a key role in the interactions between
surrounding rocks and hydraulic supports. Based
on these properties, the author proposed new definitions of basic roof and
immediate roof in top coal caving, “rock strata with deformation pressure” and “rock strata
without deformation pressure” depending on whether or not forces are posed on hydraulic supports
from the strata. The author then studied the mechanism of “combined short cantilever
beams-hinged rock beams structure” formed by the upper rock strata. From
this mechanism, the author proposed the calculation formula and influence
factors on lower limit value of hydraulic supports in top coal caving. Applying the theory in top coal caving mining for shallow coal seam,
the author also proposed the determination methods on both structures of
overlying strata and the lower limit value under different geological
conditions.
This book can be used as a reference book for both college students
and field engineers in coal mining industry.
