摘要

利用梁弯曲理论，根据岩层间变形不协调性关系，建立了坚硬顶板离层的判别条件，并指出了相应参数对顶板变形的相对影响程度。采用遥测技术监测坚硬顶板采场采空区岩层离层，结果表明，遥测系统可以有效采集到顶板岩层离层发育信息，通过监测曲线的分析，能够确定采空区顶板产生离层的位置，进而可预测出顶板垮落厚度。利用遥测系统采集到采空区顶板失稳前的离层信息，及时采取相应的措施，可保证坚硬顶板煤层安全开采。

Abstract

Based on flexure theory and inharmonic relationship of deformation of rocks

the criterion of hard roof separation was built. And the influence of homologous parameters on roof deformation was given. Using the technology of telemeter measurement to monitor rock separator in goaf

the conclusion can indicate: the system of telemeter can monitor effectively the separation information of roof rock. By anglicizing the curve monitored

the position of roof where separation happens can be confirmed; and the thickness of cave of roof would be predicted. Using the information monitored by the system of telemeter before roof cave

some prevention can be practiced to protect the safety mining under hard roof.
