As shown in Fig. 1a, the stope size is defined as 3 × 3 = 9 mining blocks, i.e. the number of mining blocks along x and y-axis is equal to 3, respectively.Given the defined stope size, a candidate mining block b may become part of 1 out of 9 possible stope combinations (for example, stopes 1 and 2). This reflects that there are numerous possible combinations for all …

A big thanks to Jeff for sharing his N scale coal mine layout. He wrote one line which really stood out for me: "Took 20 years to build, and less than a day to demolish since we were moving." Ouch! When it comes to coal mine layouts, I always think of Rich's coal mine railroad. And let's not forget John's coal mine layout.

So I thought I would put my small Hon30 layout in progress on here to see what you guys think. It is 28 in. x 53 in. As the title say it will be a mining layout. The layout is not prototypical due to space considerations and the fact that it has a lower level mine scene in it that has an oval track with a small locomotive on it.
