The tunnel was driven into the mountain far enough to reach the first vein of coal by the end of 1857. The following year the No. 9 Mine was contracted to produce 90,000 tons of anthracite coal for the company. The No. 9 Mine operated from 1855 up until June of 1972, making it the longest continuously operated anthracite coal mine in the world.

Construction of slopes and tunnels for mining purposes is one of the major sectors of our work. We have constructed many miles of slopes of various sizes both from the surface to underground and underground from location to location. Lengths have varied from a couple of hundred feet to well over a mile. Configurations have been plain unlined for ventilation, with concrete floors for rubber ...

In 1831, muledrawn wagons brought iron ore out of the woods on this path to the Morris Canal. It's hard to imagine, but 30 years later, the full scale steampowered Mount Hope Mineral Railroad pulled ore cars from this little ravine to Wharton. Its source, the Elizabeth Tunnel, is just up the trail.

Excavation began on April 6, 1903. Construction was completed October 7, 1904. The first trolley car passed through December 4, 1904. Construction for this new tunnel had begun about a year after the nearby Wabash railroad tunnel, but Booth Flinn had made such quick progress that they were finished nearly simultaneously.

Tunnel Boring Machine (TBM) A tunnel boring machine (TBM) also known as a "mole", is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock can bore through hard rock, sand, and almost anything in between. Tunnel diameters can range from a metre (done with microTBMs) to almost 16 metres to date.

RailVeyor, an innovative technology that combines the flexibility of truck hauling with the energy efficiency of conveyors and rail lines, offers mine operators and other material handlers the opportunity to dramatically cut operating costs.

Mucking machines are small compressed air operated front end loaders designed for underground mining. Mucking machines were the first that were introduced in Bisbee mines in the late 1930's to early 1940's replacing hand mucking in the crosscuts and later into some stopes.

The driving drifts (tunnels) is a very important aspect of under­ ground mining. It is not unusual for the percentage of rock broken during development in a mine, for example sublevel caving, to be as much as 25% of the total (Holmberg, 1982). If one also considers the amount broken for transport, ventilation and exploration drifts, it can
