摘 要：矿山开采沉陷是一种作用力集中、危害很大的地质灾害。它受地质条件和采矿条件等因素的影响，属于复杂的非线性力学问题，难以用数学模型描述，这给实际问题的解决带来困难。基于突变理论，研究了突变级数法在矿区地表开采沉陷损害等级预测中的应用。选取了某开采沉陷区的10个点作为样点，通过分析采空区长度、采空区宽度、开采深厚比、煤层厚度和煤层倾角等5个主要影响因素，确定预测指标体系，计算了各学习样本突变级数值。结果表明，该区开采沉陷损害A级与B级的突变级数临界值为0.91，B级与C级的突变级数临界值为0.85。利用检验样本对突变级数法的计算结果进行验证，结果和实测值基本一致，从而证明突变级数法对地表开采沉陷损害等级预测的可行性和实用性。

Abstract:Mining subsidence is one kind of geological disasters with the concentrated force and great harm.It can be influenced by geological and mining conditions and is a complicated nonlinear dynamic problem and is difficult to be predicted by mathematic models.This paper discussesed the application of catastrophe progression method on predicting the grade of surface subsidence induced by mining.In our study,10 points of some mining area were selected as sample points and predicting index system was determined and the values of catastrophe progression were calculated by analyzing 5 main factors,such as the length and width of the gob,the ratio of depth and thickness of seams mined,the thickness and dip angle of seams.The results show that the critical value of catastrophic progression for the damage of mining subsidence with Grade A and Grade B in this area is 0.91;with Grade B and Grade C,0.85.And,the calculated results with catastrophic progression method were verified with the testing samples and basically in accordance with the measured values.The results prove that the catastrophe progression method is feasible and practicable.

摘 要：为研究孤岛煤柱膏体充填开采覆岩运动规律，对岱庄煤矿2351膏体充填工作面支架压力进行了实际观测和分析。由于周围工作面回采结束时间较长，采空区内覆岩跨落后已经基本稳定。该工作面充填开采顶板初次来压步距为33.6 m，监测到的前4次周期来压步距分别为18.3、8.8、13.7、9 m。膏体充填条带煤柱开采采场与覆岩结构的特殊性决定了第一个周期来压步距相对较大。由于三面采空，虽然采用膏体充填采空区支撑上覆岩层，工作面顶板及其上覆岩层的断裂和下沉仍然十分显著。充填膏体的支撑作用使采场宏观矿压显现不明显，但三面的采空导致支架上的工作阻力较大，在推采停顿时间较长时矿压显现尤为明显。 关键词：孤岛煤柱；膏体充填；覆岩运动；来压步距 中图分类号：TD325

Abstract:In order to study the law of overburden movement during isolated coal pillar mining with paste filling,the pressures on supports in Face 2351 with paste filling in Daizhuang coalmine were observed and analyzed.Because it was a long time after mining,the overburden collapsed was basically stable in goaf around Face 2351.The first weighting spacing was 33.6 m in the face,and the spacing of first 4 periodic weighting monitored was 18.3,8.8,13.7,9 m.The special structure of the working face and overburden in paste filling strips determined that the first periodic weighting spacing was larger than others.Although the overburden was supported with filled paste,the rupture of roof and subsidence of overlying strata were quite obvious with three sides of the face being gobs.The supporting action of filled paste resulted that the macro-mining pressure was not obvious in the face,but the situation of coal mined out in three sides of the face leaded that the working resistance on supports became greater,and the ground pressure occurred more obviously,especially after the longer stop of the mining.

摘要：以济三煤矿6303工作面地质条件为背景，进行了断层冲击矿压相似模拟试验研究。利用TDS-6微震采集系统记录了试验过程微震信号，通过对微震信号频谱分析，并结合采动过程中矿压显现特征，总结提炼出断层滑移失稳微震信号的重要波形特征。试验结果表明：采动作用可诱发断层滑移失稳，如果断层围岩系统处于临界应力状态，则很小的扰动就能引起断层滑移失稳。冲击震动波传播遇到断层等不连续面时发生反射、折射，震动波部分或者完全不能穿过断层，导致在断层的另一盘监测不到震动信号。而断层滑移失稳是断层两盘发生的突然相对错动。因此，断层两盘是否监测到明显的震动信号，可以作为断层发生活化的判据。这一结论对于利用微震监测系统监测预报断层冲击矿压具有一定的借鉴意义。

Abstract:According to the geological conditions of Face No 6303 in Jining No 3 coalmine,the similar simulation test of fault rock burst was carried out.The microseismic (MS) signals were recorded by the TDS-6 MS test system.The character of MS signal waveform caused by fault slip destabilization was summarized and abstracted by using the frequency spectrum analysis method and combining with the character of abutment pressure in the process of test.The results indicate that the fault slip destabilization can be induced by coal mining operation,the fault slip destabilization will happen with even a small tremor if the fault and its surrounding rock system are in a critical state of stress equilibrium.The shock wave propagation will be reflected,refracted and absorbed by the discontinuity,such as fault plane.These make the shock wave can't go through the fault and can't be monitored in the other plate.A fault slip destabilization is a phenomenon of sudden slip between upper plate and lower plate of the fault.Based on the results,whether the clear MS signals can be monitored at two plates of fault can be a criterion of fault activity.This conclusion will generate considerable important directive significance for monitoring and forecasting the hazard of fault rock burst with MS monitoring system in coalmines.

摘 要：矸石山是煤矿区长期无序堆积的产物，稳定性极差，遇到不利条件时易发生滑坡，从而产生严重的地质灾害。由于矸石散体物理力学参数存在较大的变异性和模糊性，若采用传统的安全系数法进行稳定性分析则会存在一定风险。基于可靠度理论和模糊分析理论，提出了一种更加符合矸石山客观实际的模糊点估计可靠性分析方法，并运用该方法对重庆松藻矿区某煤矿矸石山的可靠性进行了分析。结果表明，该矸石山发生边坡破坏的可能性较大。 关键词：矸石山；稳定性；可靠指标；模糊随机可靠性；模糊点估计 中图分类号：TU457文献标志码：A

Abstract:The waste rock dump is a product accumulated by the coal wastes disorderly in mining area with its poor stability and,then,the landslide may easily occur during the disadvantageous weather conditions and accordingly cause enormous geological hazards.It was found that there were some risks when the traditional safety factor method was used to evaluate the stability of waste rock dumps because of the variability and fuzziness of physical and mechanical parameters of waste bulks.In this paper,a stability analysis method,i.e.,fuzzy point estimation method was presented based on the reliability theory and fuzzy theory.It is pracatical and effective for the stability assessment of waste rock dumps.As an example,the method was applied to evaluate the stability of a waste rock dump in Songzao Coalmine,Chongqing,showing that the failure possibility of the dump could be very high.
