| 摘 要： | 分析了大倾角条件下综放开采液压支架的受力状态与围岩的关系，以及影响支架稳定性的主要因素.针对大倾角放顶煤支架在开采过程中的受力情况，提出了防止液压支架倾倒的技术措施是：① 减少支架顶梁间隙；②在邻架顶梁间增设调架千斤顶.支架防滑的技术措施是:① 推移杆全程导向;② 相邻支架底座之间设置防滑千斤顶;③ 设置防止输送机下滑装置.

| Abstract: | Analyzed the relationship of fully mechanized top-coal caving hydraulic support's stress state and enclosing rocks under the condition of large dip angle,and the main factors of influence support stability.Aiming at stress analysis of dip angle fully mechanized top-coal caving support in mining,from the technique of designing and mining,put forward technique measurements:reduce gap of support beam;increase the inter-frame jack in neighboring support beam.Support anti-skid measures: passage of the entire process-oriented bar;set up anti-skid jack between adjacent base;set up anti-skid install for conveyor. |
