ly based on idea lised conditions that are never truly met in nature (homogenous, elastic and isotropic medium). The consequence for system design is that each system configuration, in bination with system settings, results in a specific capability to record, process and store data. Design and configuration must therefore be adapted to local requirements as formulated in the monitoring objectives. Data collection Successful system installation is followed by data gathering, which prises recording, automatic and manual processing to derive source quantification, and storage. This is a specialised field that requires input from technicians, IT system administrators and system operators under guidance of a mine seismologist. A rock engineer typically requires little knowledge of the operation of such works other than that of key indicators which would enable her to perform a review function: * 19 System down time * Station down time * Ratio accepted/rejected events * Average repair time of units * Location accuracy * Sensitivity These variables allow an effective parison of the actual system performance with preset targets that need to be monitored over time. Knowledge of methods to determine location accuracy and work sensitivity is required. At times, rock engineers may be facilitating the munication and interaction between the seismic work operator and the mine’s engineering function. For instance, on local mines only mine employed electricians are authorised to work on the electrical infrastructure to ensure uninterrupted power supply to seismic stations. 20 附錄 2 中文譯文 礦業(yè)工程師必備的能力框架 礦山地震學(xué) 南非共和國 礦業(yè)顧問公司有限公司 摘要 : 近十年來,獻身于沙特礦業(yè)的礦業(yè)地震學(xué)家數(shù)量減少了。 optimal face layout and mining sequence, production rate and face configuration to minimise seismic energy emission。在設(shè)計結(jié)尾對選出的 提升機進行了運動學(xué)和動力學(xué)校驗,保證了所選的提升機能夠穩(wěn)定、安全的運行。iF —— 提升系統(tǒng)各終止階段拖 動力( 0 1 2 3 5i? 、 、 、 、 ); 經(jīng)計算有 : 2 2 2 220222 2 2 292116177 116062 149162 143550 * 3 149215 1022427 10 NXT F dts??? ? ? ? ???????? ? ? ?? ? ?式( ) 提升機等效力為: 2 90 4 2 7 1 0 8 9 . 0 9 8 k N5 3 . 9XTd dF d tF T? ?? ? ? 式( ) 電動機容量為 201000 * 81 .8 2310 00 * 0. 85 15 59 .4 5xTmdjdF dtvPTkW????? 式( ) 電動機容量的驗算 1) 按電動機允許發(fā)熱條件 / 1dPP?? 式( ) 7 即有 %的備份容量。 5 7 提升系統(tǒng)相關(guān)參數(shù)校核及驗算 提升電動機容量校核 提升電動機的工作狀態(tài)屬于重復(fù)短時工作制,提升電動機工作軸上的功率不僅每個提升循環(huán)有變化,而且在每個循環(huán)工作系統(tǒng)中也是變化的。該系統(tǒng)核心部分為單繩纏繞式提升機。這種提升設(shè)備特別適合于較深礦井中。 19 世紀,歐洲率先出現(xiàn)蒸汽機,資本主義國家采用了蒸汽拖動的礦井提升設(shè)備。設(shè)計要求根據(jù)該礦井深,礦井年產(chǎn)量等原始參數(shù),進行礦井主井提升設(shè)備的選型設(shè)計計算。 提升速度圖分析 ...................................... 錯誤 !未定義書簽。 提升機與井筒的相對位置計算 .......................... 錯誤 !未定義書簽。 天輪的選擇計算 ......................................... 錯誤 !未定義書簽。 提升鋼絲繩 .......................................... 錯誤 !未定義書簽。 本設(shè)計主 要對礦井主井生產(chǎn)所用的提升設(shè)備進行的一次合理選型。 關(guān)鍵詞 雙卷筒;單繩纏繞式提升機;鋼絲繩;天輪 II Abstract Mine Hoisting equipment is used to lift the coal mine, waste rock, person and equipment and set down material along the shaft ,is a throat.contacted of mine up and down.
