Saturated water coal mixture is controlled by multiple factors such as water source, coal feature, potential energy and time etc. The water coal burst disaster is characterized by paroxysm, large energy, persistent short time and stronger explosive force,it takes place only under some special background. In extremely inclined coal seam districts, faces are generally arranged under water prevention coal pillars, it is quite possible for the water coal burst disaster to take place, because mining inbreak heights are easy to reach location of the water coal mixture. On the basis of analysis of the disaster mechanism, some efficient prevention and cure countermeasures for the water coal burst disaster in coal mines is put forward.

水煤体是在水源、煤性、位能和时间等因素的综合作用下形成的处于饱和状态的水、煤混合体 .水煤体溃泄是一种具有突发性、能量大、持续时间短、爆发力强和损失惨重等特点的发生于特殊背景条件下的矿井灾害 .在急倾斜煤层分布区 ,工作面布置于防水煤柱下方 ,煤层回采导致的顶板冒落带发育高度极易接近上覆水煤体 ,故极有可能诱发水煤体溃泄的灾害性事故 .在水煤体溃泄机理分析研究的基础上 ,提出了防治煤矿井水煤体溃泄灾害发生的若干有效对策

The numerical analogy has been adopted to study the mechanic features influencing stress distribution in coal and rock around the roadway in order to control rock burst disasters. The research indicates that volume modulus, cohesion and internal friction angle of coal seam around the roadway have a great influence on stress distribution. Based on this conclusion, the state of stress distribution can be changed and the rock burst can be limited or avoided by applied shock failure method.

为了治理冲击矿压灾害,采用数值模拟方法研究了井巷周围煤岩体的力学特性对应力分布的影响。研究结果表明,巷道周围煤岩体的体积弹模、内聚力和内摩擦角均对应力分布有较大的影响。根据这个结果,可采用卸压爆破的方法,改变应力分布状态,减小或消除冲击矿压危险。

In this article, writers put forward the method of pressure relief cave in avoiding rock-burst disaster induced by mining. The emphasis of the method is that we can weaken coal body factitiously at some given places and ensure that rock-burst will occur at those places. While the rock-burst occurred at those given places, the excrescent energy of the system will be released, thus achieving the goal of prevention and cure of rock-burst disaster.

就在采矿、掘进等岩土工程活动中诱发冲击地压特点及其破坏特征进行了论述。提出了一种经济、有效而可行的防治冲击 地压成灾的卸压洞法。同时又从岩石力学系统稳定性角度,对其进行了理论分析。该法从本质上是在矿山采掘活动中以人为定点开挖 卸压洞来弱化煤体,使由采掘诱发的冲击地压在预定点发生,释放其周围系统中的大部分能量。即在人为预定点放灾而达到控制或防 治冲击地压灾害的目的。
