| 1 | 放顶煤液压支架承载特性及其适应性分析显示文摘通过对两柱、四柱式放顶煤液压支架支架结构特征分析,研究了不同工作阻力两柱式放顶煤液压支架、相同工作阻力两柱和四柱式放顶煤液压支架承载特性和其影响因素,并对液压支架适应性进行分析。研究结果表明:液压支架的结构特性决定其承载特性,两柱式放顶煤液压支架平衡千斤顶机构决定其有效承载范围在顶梁柱窝附近,增大立柱和平衡千斤顶的工作阻力能增大其承载能力,但通过增大平衡千斤顶工作阻力改变支架承载能力有限;四柱式放顶煤液压支架两排立柱与顶梁铰接位置决定其有效承载范围与立柱排距相当,增大前柱工作阻力降低后柱工作阻力能提高支架顶梁前段支撑能力,使支架有效承载范围前移;液压支架承载特性决定其适应性。平衡千斤顶能适时调节两柱式放顶煤液压支架顶梁上顶板荷载作用的位置,使其能适应一般综放工作面,但特厚煤层大采高综放工作面顶板荷载受顶煤放出影响作用位置多变,易导致平衡千斤顶损坏,四柱式支架有效承载范围较宽,使其能适应特厚煤层大采高综放工作面。 | 李化敏 蒋东杰 Syd S Peng 冯军发 | 2015 | 煤炭科学技术2015，43，6： | 33 |
| 2 | 基于海量矿压监测数据的采场支架与顶板状态智能感知技术显示文摘超前感知综采工作面顶板来压并预判冒顶事故、自主评价支护参数的适应性,是提高综采工作面安全高效及智能化水平的基础。围绕综采工作面支架与顶板状态智能感知的核心问题,基于综采工作面电液控制液压支架海量监测数据,开发了综采工作面支架与顶板状态智能感知系统(SSRI);结合大数据挖掘及工作循环分析技术,提出了用于支架压力分析的多因次工作循环特征参数;研究了安全阀开启、割煤及邻架移架、地质等多种因素影响下的单台支架承载特征及支架群组载荷转移分布规律;在深入解读支架阻力及活柱下缩时序曲线所蕴含的支架与围岩相互作用关系的基础上,构建了支架与顶板状态智能感知模型,实现了对顶板来压的预测、冒顶预警、支架适应性及支护质量评价,初步建立了基于海量矿压监测数据的采场支架与顶板状态智能感知技术体系。结果表明:①额定工作阻力不应作为评价支架承载能力的惟一或主要指标,初撑力、额定工作阻力及安全阀开启特性等参数共同决定了支架的承载特性及承载能力;②充分挖掘分析海量矿压监测数据,可以实现采场顶板灾害智能预警、支护质量评价及故障诊断等研究目标;③对海量监测数据的深入分析与利用是实现综采工作面支架围岩耦合自适应控制、支护参数自适应调整等智能化开采目标的前提与基础。 | 程敬义 万志军 PENG Syd S 张洪伟 邢轲轲 闫万梓 刘泗斐 | 2020 | 煤炭学报2020，45，6： | 17 |
| 3 | 美国煤炭地下开采与自动化技术进展显示文摘美国煤炭的地下开采分为长壁式和房柱式2种技术。地质条件较好、井田范围大的矿井,一般以长壁开采为主,否则以房柱开采为主。1994—2017年,美国井工矿数量减少了79%(2017年为237座)。但是单个矿井产量增加了230%,煤炭生产更加集中、高效。美国长壁开采以中厚煤层为主,采高一般为1.6~2.5 m(最大开采高度4.2 m,最小开采高度1.2 m)。长壁工作面均采用多巷布置、矩形断面巷道、锚杆支护。近年来,工作面尺寸、设备功率、设备尺寸逐渐增大,生产系统更加可靠。长壁工作面的自动化开采源于1984年的电动控制液压支架的研发与使用,此后开发了支架、采煤机、刮板输送机的单机自动化以及追机移架技术。2000年以后开发了半自动化工作面技术和采煤机远程控制技术。目前应用的主要是半自动化工作面技术,只有2个工作面应用了采煤机远程控制技术。这些技术解决了条件简单工作面的自动化开采问题,但遇到复杂地质条件时,仍需要人工干预。研发自动化开采的关键传感器和设备以适应地质条件变化、完善端部进刀系统,聚焦作业安全和粉尘与噪音防控,以及矿用大数据、高速通信与可视化技术是目前美国的重要研发方向。在近10 a来,房柱开采的工艺变化不大,但是开采装备的多样化和开采系统的自动化、信息化、智能化的相关技术开发取得了重要进展。 | 王家臣 PENG Syd S 李杨 | 2021 | 煤炭学报2021，46，1： | 16 |
| 4 | 神东矿区岩石物理力学性质变化规律研究显示文摘通过对神东矿区3个典型大采高工作面钻孔柱状岩石物理力学性质与沉积时期和埋深关系的研究,得到如下结论:1)埋深相同的同类岩性岩石的物理力学性质与沉积时期有着密切联系,同矿区不同矿井同一岩性即使在同一埋深条件下,其岩石物理力学性质也有很大的不同,沉积时期早的岩石物理力学性质大于沉积时期晚的岩石;2)同类岩性岩石的物理力学参数总体上随着埋深的增加而增加,且大多数岩石的物理力学性质与埋深具有较好的线性关系;3)同一矿井的砂岩类抗压强度和抗拉强度与颗粒粒径成反比,且泥岩类的抗压强度和抗拉强度普遍比粗砂岩和含砾粗砂岩高。 | 杜锋 Syd S PENG | 2019 | 采矿与安全工程学报2019，0，5： | 10 |
| 5 | Trial of small gateroad pillar in top coal caving longwall mining of large mining height显示文摘Coal seams in Tashan Mine of Datong Coal Group in China average 15 m thick and have been mined by the top coal caving longwall mining method of large mining height. Mining height was 3.8 m and the top coal caving height was 11.2 m. The gateroad pillar between panels was 38 m. During retreat mining,serious bumps occurred in the gateroads on both sides of the pillar affecting safety production. Therefore,pillarless mining was experimented. Using numerical modeling and comparative study of cases of similar mining condition,it was decided to employ a 6 m wide pillar,rather than the previous 38 m wide pillar.Support system for the gateroads was designed and implemented. During gateroad development,pillar failure conditions and entry deformation were monitored. Hydraulic fracturing method was employed to cut off the K3 sandstone along the entry rib so as to reduce the abutment pressure induced during retreat mining. Support reinforcement method combining grouting and advanced reinforcement methods was proposed to insure stable gateroad ahead of mining. Methane drainage and nitrogen injection were implemented to eliminate hazards associated with mine fire and spontaneous combustion. Since the development of gateroad has just completed,and retreat mining has not begun,the effectiveness of the proposed methods is unknown at this point. However,monitoring will continue until after mining.The results will be published in a separate paper. | Li Huamin Syd Peng Li Huigui Xu Yongxiang Yuan Ruifu Yue Shuaishuai Li Kun | 2016 | International Journal of Mining Science and Technology2016，26，1： | 8 |
| 6 | What can the changes in shield resistance tell us during the period of shearer's cutting and neighboring shields' advance?显示文摘In order to determine the influence of shearer's cutting and neighboring shields' advance on the support resistance variation, leg pressure data of all 235 shields in the panel LW61 of Cumberland coal mine were analyzed. The results show that the relationship between the leg pressure increment and the distance from shield to front drum of shearer is a quadratic function and that the higher leg pressure increment before shield advance tends to be related to adverse roof conditions. In addition, the three proposed leg pressure increment-related parameters and the three traditional parameters(time-weighted average pressure, setting pressure, and final pressure) of approximately 32000 shield supporting cycles were calculated by a self-developed software package to analyze the correlation between them. The results show that there is a powerful connection between them, and that the three proposed leg pressure increment-related parameters could be used as the indexes to evaluate the interaction between shields and the roof, and to identify the periodic weighting. | Cheng Jingyi Wan Zhijun Peng Syd S.

| 9 | Roof bolting and underground roof falls显示文摘Roof bolting has been used in underground entry(roadway)support in U.S.coal mines since the Coal Mine Health and Safety Act of 1969(US Congress,1977)recognized roof bolting as the only means of underground entry(roadway)support.For U.S.underground coal mines,roof bolting pattern is fixed at 44 ft(1.21.2 m),except in the Pittsburgh Seam where longwall mining is practiced,with occasional 3.64 ft(1.11.2 m)pattern.However,roof falls or roof failure often occurs in roof-bolted entries in U.S.coal mines.Roof falls can roughly be divided into four types:skin falls,large falls,cutter roofs,and massive falls.Based on this situation,the roof is initially strengthened by bolt based on suspension and friction mechanism.By comparing roof bolting patterns in different coal producing countries,bolt density in all other countries is much higher(except South Africa)than that used in the U.S.In spite of its long history of successful application with hundreds of millions of units installed,roof bolting design is still the lack of a commonly accepted method. | Syd Peng | 2023 | Geohazard Mechanics2023，1，1： | 0 |
