1 The miners had to crawl to reach the coalface.

2 Academics will be working at the coalface alongside the doctors.

3 At the coalface with a deadline looming, you sometimes feel under a lot of pressure.

4 At the coalface your guides will explain the different methods of extracting coal and the working conditions of the miners.

5 His grandfather worked the coalface and his father was a Miners' Union official.

6 The length of the first coalface in a mining-district controls the distances of first weighting and periodic weighting of the main roof.

7 These conclusions are confirmed by 1203 coalface in which water bursting occur but sand bursting not when mining.

8 Coalface of Daizhuang Coalmine, the authors believe that the roof in lower seam will form the"block-bulk-beam"structure easy to fall after the mining of top ultra-close seam.

9 Gas explosion accidents on the coalface of mines are studied, using minimal cut set, minimal radius set and structural importance.

10 Aimed at the shortcomings of coalface passing through fault as low speed, low efficiency and low-quality coal and so on,[www.Sentencedict.com] a new technique was suggested.

11 Many of the best ideas come from doctors at the coalface.

12 I have tremendous admiration for anyone who has spent a lifetime in the mining industry, especially at the coalface.

13 Further investment is needed to allow the consortium to open another coalface to speed up production.

14 In order to determine the dynamic load on key roof of coalface in simulating model test, the intelligent dynamic load data real time acquisition system is developed.

15 The gas transport process in tunnel and the cause of gas accumulation at the upper corner of coalface are described.

16 More commonly, however, they reflect the desires of user "representatives" who are too far removed from the coalface to know the details of the real work.

17 And intriguingly, it is the BPM vendors themselves who are pushing spreadsheets back up to the coalface of finance.

18 It has been proved by the field experiment that the method of rotary radial jet discharging gas accumulating in upper corner of coalface is really safety, dependable, economical and validly.

19 The position and state of the main roof above the terminal line of the coalface nearby the rises affect the magnitude of the peak abutment pressure and the difficult extent of the rise maintenance.

20 Based on some typical examples of gas explosions on the coalface, the basic events resulting in gas explosions are generalized and a fault tree is drawn.

21 To solve strata pressure control of shallow coal seam with thick sand and thin bedrock, in-situ observation was carried out in Baoshan mine 6101 fully mechanized coalface, which is the first coalface.

22 The mechanical model of key strata supported by coal pillar is set up according to the layout of coal pillars in the coalface of short wall mining.

23 At the small Bandingliang colliery, the pit has been dug so far into the hillside that truck drivers take 30 minutes to reach the coalface, fill up and return with their load.

24 Firstly, The simulation of Craftwork Process of Fully Mechanized Coalface is studied in the thesis and then analyses Craftwork Process of Fully Mechanized Coalface by using the Object-Oriented method.

25 It provides a new model to guide the on-spot work and do safety education for workers by vividly simulating Craftwork Process and complex environment of Fully Mechanized Coalface.

26 Through analyzing Principal Component Analysis(PCA) and Gene Expression Programming(GEP), a novel GEP Algorithm based on PCA is proposed and applied to predict the amount of gas emitted from coalface.
