Three stopes with different spans (8m , 16m, 24m ) were selected for the purpose of stress study with epoxylite model . The distributions of roof stress under the condition of 1×0.8m support grid compared with unsupporting , and that of roof bolting patterns of 0.8×0.8m, 1×0.8m, 1.6×0.8m were also investigated . Finallg , the authors evaluate the practical effects of roof ?

采用环氧树脂模型研究了三种不同跨度(8米、16米、24米)采场，在支护网度为1×0.8米~2及无锚杆护顶时顶板应力分布状况，同时也研了在相同条件下，锚杆支护网度为0.8×0.8米~2、1.6×0.8米~2时顶板应力分布状况，从而阐明了锚杆支护的实际效果。

Based on the theory of hanging on laneway roof with roof bolt and taking the bolt as base point, this new preceding support can work in the free space on the laneway roof, allowing other equipments such as the entry-driving machine work at the same time, thus improving the utilizing efficiency of the laneway. On the cirques track of bolts, its three groups of claw, which are driven by hydraulic force, work as fulcrums to one another to push the support move forward.

基于顶板锚杆悬挂理论，以锚杆为基点，采用自制圆形梁为执道，以液压力驱动3组机爪互为支点实现超前支架在巷道顶部空间的迈步前移，采用具有顶板适应性的变运动方向平行四边形机构作为超前支护机构，来实现超前支架的支护作业。

With the increasing of the bedrock thickness, pressurized pace was increased gradually, the roof caving and surface subsidence were gentled step by step. When the thickness of roof bedrock was larger than 60m, the bench subsidence was not occurred, and the value of surface subsidence was also small. The mining technology was proper and highly active, and the support programme was feasible. The roof was controlled effectively by the support system, and achieved safety mining.

随着基岩厚度的增加，顶板来压步距逐步增加，顶板垮落与地表下沉越来越缓和，基岩厚度大于60m时，顶板来压不再出现台阶下沉，地面下沉量较小；针对不同厚度基岩提出的采煤方法合理，高效，支护方案可行，能够有效控制顶板，实现安全生产。
