Based on field measurement, the authors describe zone of influence of abutment pressure, rules of its change, loosening of the surrounding rock and the stability of roadways. Mechanism of this support system is also discussed. It forms an integral and flexible structure with the surrounding rock and has a better adaptability to the influence of coal extraction than any other support. When abutment is not evident, rock-bolting and shotcreting is feasible. When abutment is heavy, it is better to use mainly rock-bolting...

Mechanism of this support system is also discussed. It forms an integral and flexible structure with the surrounding rock and has a better adaptability to the influence of coal extraction than any other support. When abutment is not evident, rock-bolting and shotcreting is feasible. When abutment is heavy, it is better to use mainly rock-bolting with wire mesh supplemented with shotcreting. When abutment is very heavy, ordinary bolting and shotcreting can hardly applied with success, combined support system should be adopted.

本文以现场量测为依据,论述了岩石巷道的锚喷支护受采动影响时,移动支承压力的影响范围、变化规律、围岩松动以及巷道稳定性等。探讨了锚喷支护对采动影响的适应机理。锚喷支护与围岩形成一个具有一定柔性的整体,其对于采动影响比别种支护有较大的适应性。移动支承压力不大时,采用锚喷支护是可行的;移动支承压力较大时,以采用锚网联合支护为主,敷之以喷为好;移动支承压力特大时,一般的锚喷支护难以取得良好的效果,应研究采用与其它支护相结合的方式。

The supporting of permanent openings has been a difficult problem in production and technique for many years. The lining support commonly used in practice is poorly water proof, short life and needs constant maintenance, so it seriously interferes with the production of underground mine. According to the basic properties of soft rock, a combining support method is investigated by means of computer simulation and in-situ measurements.

The supporting of permanent openings has been a difficult problem in production and technique for many years. The lining support commonly used in practice is poorly water proof, short life and needs constant maintenance, so it seriously interferes with the production of underground mine. According to the basic properties of soft rock, a combining support method is investigated by means of computer simulation and in-situ measurements. As a matter of fact, this method is shown to be applicable especially to support the permanent opening in soft rock. It has been found in a permanent opening supported by this method after three years of service that the surrounding rocks tend to be stable, gallery is in good condition and the equipments run perfectly well. In addition, this method not only achieve benefits technically and economically, but is also promising for supporting the permanent opening in soft rock with rich underground water.

永久洞室的支护方法,多年来一直是松软岩层矿井生产的技术难关。常规的干砌料石支护,隔水性能差、寿命短、维修量大,严重地影响生产。作者针对松软岩层围岩变形特性,通过长期的现场量测,以及计算机模拟检验等手段,对联合支护方法进行了较全面的考察,证实该方法适用于松坎岩层永久洞室的支护。 联合支护的永久洞室投入使用五年来的实践表明。围岩变形趋于稳定,巷道状态良好,设备运行正常,在技术上和经济上都取得了较好的效益。为解决地下水丰富的松坎岩层矿井的永久支护奠定了良好基础。

A so called bolt-beam-net support system is a combined support form which is using split set bolts,steel-plate beam and plastic net for roof support of a gateway and using polyurethane wooden bolts (or cement bamboo bolts), roof bolt plates and bamboo net for both side ribs.

A so called bolt-beam-net support system is a combined support form which is using split set bolts,steel-plate beam and plastic net for roof support of a gateway and using polyurethane wooden bolts (or cement bamboo bolts), roof bolt plates and bamboo net for both side ribs. In Jietai Mine of Xuzhow Coal Mine Administration, this support system has been used in gateways in 'three soft' (i.e.soft roof, soft rib and soft floor) seam for an industrial trial. Good results have been achieved from the trial. This paper presents detailed informations on the trial gateway conditios, operation of the boltbeam-net support system, measured results of the mine pressure on the gateway, analysis of the measured results and analysis of the technical and economic results. This practice has shown that this combined support system can effectively control the surrounding rocks of the gateway. It also shows that it's feasible in technology and reasonable in economic.

作者从试验巷道条件、锚梁网支护施工方法、巷道矿压观测结果及其分析、技术经济效果分析等几方面进行了叙述。
